OPTICAL RANGEFINDER AN IMAGING APPARATUS WITH CHIRAL OPTICAL ARRANGEMENT

WIPO Patent Application WO/2010/080030

A3

The invention relates to an optical rangefϊnder comprising a photosensor adapted to transform the image projected onto it into an electronic image, an imaging system for projecting an image of an object on the photosensor, an optical arrangement to modulate the incoming light forming the image on the photosensor, means for providing the spatial spectrum of said image and means for deriving the distance from the object to the range finder on the degree of defocus of the image, wherein the optical arrangement is adapted to modulate the incoming light such that the degree of defocus of the image on the photosensor relative to the in-focus image plane results in displacement of the spatial spectrum of said image relative to a reference pattern and wherein the rangefinder comprises means for deriving the degree of defocus from said degree of displacement.
