SPIE publishes an article on curved sensor optics benefits "Current trends in miniature camera lens technology" by Dmitry Reshidko and José Sasian. The curved sensor are said to give a 1-stop advantage due to allowing optics with a larger aperture: |
| MTF of a mobile camera. (a) Conventional flat field design at f/2.2. (b) Representative lens imaging on a curved sensor at f/1.6. The lens imaging on a curved sensor is one f-number faster and shows more uniform performance over the field. OTF: Optical transfer function. |

| Sensitivity to lens element decenter (left) and tilt (right). Lens imaging on a curved sensor shows better as-built performance. The horizontal line indicates the nominal criterion value. RSS RMS: Root sum square, root mean square. |
