Abstract:
A high-precision-resolution image acquisition apparatus, said apparatus comprising:a support surface for supporting an object to be imaged;a camera supported at an optical distance from said support surface for acquiring an image of an object being imaged, said camera outputting a signal representing the image of said object being imaged and said camera having an optical path along which said image is acquired and a field of view, said image having a resolution and said optical distance being adjustable such that the resolution of said image can be adjusted;computer means for analyzing said signal to determine the resolution of said image;a first light source which projects a first beam of light so as to strike said object being imaged at a first location on a surface of said object being imaged, said first light source being configured such that said first location varies as said optical distance is adjusted; anda second light source which projects a second beam of light so as to strike said object being imaged at a second location on said surface of said object being imaged,wherein one of said first and second light sources is a line laser and the other of said first and second light sources is a cylindrical beam laser which projects a dot or spot of laser light on said object being imaged.
