Abstract:
A micro-scanning multislit confocal image acquisition apparatus comprising:a nonscanning multislit confocal image acquisition system that uses a slit array consisting of a plurality of two-dimensionally arrayed slit apertures, an objective lens that causes illumination light passing through said slit array from behind to converge so as to form an image of said slit array on the surface of the object measured and also causes the light reflected from the surface of the object to converge toward said slit array, and a two-dimensional arrayed photodetector for detecting the amount of light that passes through each slit aperture of a slit array disposed at the same position optically as said slit array anda multislit-image microscanning mechanism for moving the image of said slit array in a small back and forth motion with respect to the object during each exposure of said two-dimensional arrayed photodetector in one complete measurement.
