Front illuminated vs back illuminated
A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing. The matrix and its wiring, however, reflect some of the light, and thus the photocathode layer can only receive the remainder of the … WebMar 30, 2024 · Although both are similar in name and components, each uses a slightly different method to achieve performance. Exmor sensors use a front-illuminated structure and are layered in the following order: Exmor R sensors use a back-illuminated structure with the same layers, but in a different order: In Exmor R sensors the position of the …
