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 … WebThe QHY183C camera uses the back-illuminated Exmor R Sony IMX183 20MP sensor for higher sensitivity and quantum efficiency than traditional front-illuminated designs.
