  • High-precision-resolution image acquisition apparatus and method
    Patent number: 6320641
    Abstract: A method and apparatus for setting and repeatably and reliably maintaining a desired image resolution. The invention features an optical, image acquiring device and a pair of light sources, the beams from which are caused to converge at a distance from the optical device which provides the desired resolution. Subsequently, positioning the optical device with the point of convergence of the beams on the surface of an object being imaged ensures the desired resolution. In preferred embodiments, the plane yielding the desired resolution is caused to be coincident with the plane of optimal focus.
