Imaging Resource on Nikon Image Sensor Design

Image Sensors World        Go to the original article...

Imaging Resource publishes a very nice article "Pixels for Geeks: A peek inside Nikon’s super-secret sensor design lab" by Dave Etchells. There is quite a lot on Nikon-internal stuff that has been publicly released for the first time. Just a few interesting quotes out of many:

"Nikon actually designs their own sensors, to a fairly minute level of detail. I think this is almost unknown in the photo community; most people just assume that “design” in Nikon’s case simply consists of ordering-up different combinations of specs from sensor manufacturers.

In actuality, they have a full staff of sensor engineers who design cutting-edge sensors like those in the D5 and D850 from the ground up, optimizing their designs to work optimally with NIKKOR lenses and Nikon's EXPEED image-processor architecture.

As part of matching their sensors to NIKKOR optics, Nikon’s sensor designers pay a lot of attention to the microlenses and the structures between them and the silicon surface. Like essentially all camera sensors today, Nikon’s microlenses are offset a variable amount relative to the pixels beneath, to compensate for light rays arriving at oblique angles near the edges of the array.

Apparently, Nikon uses Silvaco tools for pixel device and process simulations:

Four Challenges for Automotive LiDARs

Image Sensors World        Go to the original article...

DesignNews publishes a list of four challenges that LiDARs have to overcome on the way to wide acceptance in vehicles:

Price reduction:

Every technology gets commoditized at some point. It will happen with LiDAR,” said Angus Pacala, co-founder and CEO of LiDAR startup Ouster. “Automotive radars used to be $15,000. Now, they are $50. And it did take 15 years. We’re five years into a 15-year lifecycle for LiDAR. So, cost isn’t going to be a problem.

Increase detection range:

Range isn’t always range,” said John Eggert, director of automotive sales and marketing at Velodyne. “[It’s] dynamic range. What do you see and when can you see it? We see a lot of ‘specs’ around 200 meters. What do you see at 200 meters if you have a very reflective surface? Most any LiDAR can see at 100, 200, 300 meters. Can you see that dark object? Can you get some detections off a dark object? It’s not just a matter of reputed range, but range at what reflectivity? While you’re able to see something very dark and very far away, how about something very bright and very close simultaneously?

Improve robustness:

It comes down to vibration and shock, wear and tear, cleaning—all the aspects that we see on our cars,” said Jada Smith, VP engineering and external affairs at Aptiv, Delphi spin-off. “LiDAR systems have to be able to withstand that. We need perfection in the algorithms. We have to be confident that the use cases are going to be supported time and time again.

Withstand the environment and different weather conditions:

Jim Schwyn, CTO of Valeo North America, said “What if the LiDAR is dirty? Are we in a situation where we are going to take the gasoline tank from a car and replace it with a windshield washer reservoir to be able to keep these things clean?

The potentially fatal LiDAR flaws that need to be corrected:

  • Bright sun against a white background
  • A blizzard that causes whiteout conditions
  • Early morning fog

Omnivision Releases Sensor Optimized for Structured Light FaceID Applications

Image Sensors World        Go to the original article...

OmniVision announces a global shutter sensors targeting facial authentication in mobile devices, along with other machine vision applications such as AR/VR, drones and robotics. The high-resolution OV9286 sensor, with 20% more pixels than the previous-generation sensor, is said to enable a new level of accuracy in facial authentication for smartphone applications requiring the high levels of security. The OV9286 is optimized for payment-level facial authentication using a structured light solution for high-quality 3D images.

The market for facial recognition components is expected to grow rapidly to $9.2b by 2022, according to a report from Allied Market Research.

A higher level of image-sensing accuracy is required to safely authenticate smartphones for payment applications, compared to using facial authentication for unlocking a device,” said Arun Jayaseelan, senior marketing manager at OmniVision. “The increased resolution of the OV9286 image sensor meets these requirements, while using the global shutter technology to optimize system power consumption as well as to eliminate motion artifacts and blurring.

The sensor is available in two versions: the OV9286 for smartphone applications, and the OV9285 for other machine vision applications that also need high-resolution sensors to enable a broad range of image-sensing functions. The OV9286 has a high CRA of 26.7 degrees for low z-height and slim-profile smartphone designs. The OV9285 has a lower CRA of 9 degrees for applications where that tight z-height restriction does not apply, supporting wide field-of-view lens designs.

Both the OV9285 and the OV9286 incorporate 1328 x 1120 resolution at 90 fps, an optical format of 1/3.5-inch and 3x3-micrometer OmniPixel3-GS technology. These global shutter sensors, in combination with excellent NIR sensitivity at 850 nm and 940 nm, reduce device power consumption to extend battery life.

The OV9285 and OV9286 sensors are available now.

3D Imaging Fundamentals (Open Access)

Image Sensors World        Go to the original article...

OSA Advances in Optics and Photonics publishes "Fundamentals of 3D imaging and displays: a tutorial on integral imaging, light-field, and plenoptic systems" by Manuel Martínez-Corral (University of Valencia, Spain) and Bahram Javidi (University of Connecticut, Storrs).

"This tutorial is addressed to the students and researchers in different disciplines who are interested to learn about integral imaging and light-field systems and who may or may not have a strong background in optics. Our aim is to provide the readers with a tutorial that teaches fundamental principles as well as more advanced concepts to understand, analyze, and implement integral imaging and light-field-type capture and display systems. The tutorial is organized to begin with reviewing the fundamentals of imaging, and then it progresses to more advanced topics in 3D imaging and displays. More specifically, this tutorial begins by covering the fundamentals of geometrical optics and wave optics tools for understanding and analyzing optical imaging systems. Then, we proceed to use these tools to describe integral imaging, light-field, or plenoptics systems, the methods for implementing the 3D capture procedures and monitors, their properties, resolution, field of view, performance, and metrics to assess them. We have illustrated with simple laboratory setups and experiments the principles of integral imaging capture and display systems. Also, we have discussed 3D biomedical applications, such as integral microscopy."

OSA Advances in Optics and Photonics site also has a 2011 open access paper "Structured-light 3D surface imaging: a tutorial" by Jason Geng. Since the structured light approach has progressed a lot over the recent years, the information in this tutorial is largely obsolete. Still, it could be good start for learning basics or for history-inclined readers.

Leti-SNRS Full-Frame Curved Sensor Paper

Image Sensors World        Go to the original article...

Leti-SNRS curved sensor paper "Curved detectors developments and characterization: application to astronomical instruments" by Simona Lombardo, Thibault Behaghel, Bertrand Chambion, Wilfried Jahn, Emmanuel Hugot, Eduard Muslimov, Melanie Roulet, Marc Ferrari, Christophe Gaschet, Stephane Caplet, and David Henry is available on-line. This work was first announced a year ago.

"We describe here the first concave curved CMOS detector developed within a collaboration between CNRS-LAM and CEA-LETI. This fully-functional detector 20 Mpix (CMOSIS CMV20000) has been curved down to a radius of Rc =150 mm over a size of 24x32 mm2. We present here the methodology adopted for its characterization and describe in detail all the results obtained. We also discuss the main components of noise, such as the readout noise, the fixed pattern noise and the dark current. Finally we provide a comparison with the flat version of the same sensor in order to establish the impact of the curving process on the main characteristics of the sensor.

The curving process of these sensors consists of two steps: firstly the sensors are thinned with a grinding equipment to increase their mechanical flexibility, then they are glued onto a curved substrate. The required shape of the CMOS is, hence, due to the shape of the substrate. The sensors are then wire bonded keeping the packaging identical to the original one before curving. The final product is, therefore, a plug-and-play commercial component ready to be used or tested (figure 1B).

"The PRNU factor of the concave sensor shows an increase of 0.8% with respect to the flat sensor one. The difference between the two is not significant. However more investigations are required as it might be due to the curving process and it could explain the appearance of a strong 2D pattern for higher illumination levels."
