Is any cmos image sensor able to detect red laser beam ? Actually I want the image sensor to detect the red laser beam on finger nail. This concept is just like "LASER VIRTUAL KEYBOARD". When finger is down to press the keyboard, the image sensor senses that is a red beam on nail and then take some reading and produce output.

I need a cmos image sensor which able to perform like that and also can be programmed by PIC(microcontroller, MPLab). Please help me.... urgent.

    Almost any color video sensor will be able to detect a red laser beam. Interfacing it to a PIC will most likely require a fast adc chip to digitize the video signal.
