Fujifilm develops a new multispectral camera based on polarization-sensing image sensor:

  • High-performance multispectral camera system is equipped with a lens fitted with newly-developed filters, a polarization image sensor that can capture specific directional polarization image, and a cutting-edge image processing function. This system can simultaneously record images of different wavelength ranges in high definition and presenting them in real time.
  • The newly-developed filters serve as “polarizer” that lets light in a specific direction of polarization pass through as well as “optical bandpass filter” that passes light of a specific wavelength range. The system uses three filters to split light into up to nine wavelength bands, while also polarizing the light of each wavelength band into a specific oscillation direction. (Figure 1)
  • The polarization information of light in each wavelength band that has passed through the filters is recorded by the polarization image sensor and applied with the cutting-edge image processing function for visual presentation in high resolution and at a high frame rate (Figure 2). The system also allows users to choose an optical bandpass filter of the optimum wavelength band for their monitoring object.


Once we are at polarization sensing devices, OSA Image of the Week shows a nice visualization of mechanical stresses in plastic cutlery:
