HI,I want to ask how CCD work in Sharp IR sensor like GP2D12?
The sharp IR sensor shoots out a concentrated (by the lens) IR-light beam
The beam hits an object, and reflects back in all directions.
As the length from the object increases, the returning lights degree will be steeper.How the beam that hit the CCD,translate into length(x in my figure) or into angle?
I can measure the X by the hit pf the beam?
I know the b(the length between the eye and the ccd of the sensor) so i can know with b and the x the length the object is.
Thank u and sorry for the mistakes in english.
