Abstract
The present invention is directed to a distortion free imaging device having an imaging optical system that could be utilized for example in a video camera. In particular a camera configured according to the present invention reduces or eliminates the positive or pin cushion distortion that makes figures seem fatter than they really are. The imaging device includes a photosensor that is configured entirely along the contours of the posterior focal plane of the imaging optical system. The optical system can include a single or plurality of lens and can include a mirror.
Claims20
An imaging device, comprising:
- an optical system having a posterior focal area;
- and
- an irregularly shaped photosensor configured to conform to and substantially occupy said posterior focal area.
A method of compensating for distortion in an imaging system having an optical system and an irregularly shaped photosensor, said method comprising the steps of:
- (a) inputting a plurality of light rays to said optical system over an area of said optical system;
- (b) diffracting each of said input light rays from said area of said optical system;
- and
- (c) transmitting each of said diffracted light rays to one of a plurality of photosensor devices located at a plurality of irregular posterior focal points corresponding to said area of said optical system.
