Optical design of multi channel CCD cameras

Optical design of multi channel CCD cameras A projector is an output device which is producing light – which is contrary to the concept of a camera. A camera captures the light and directs it onto light sensitive elements on the CCD.

 

When using a 3 CCD camera the spectrum of the light is split into different bands of wave lengths  - each falling onto a dedicated CCD camera. This improves spectral performance of the camera – so it is possible to see UV or IR light which cannot be seen with the human eye.

 

Such cameras are used for medical, security, night vision systems.
