Alignment procedure of an object with an image sensing device and a coupling optic

摘要

Procedure for optimum alignment of an object with image acquisition device and coupling optics. Procedure comprises definition of an object plane (6), emission of at least 3 point light sources (1a,1b) in the object plane (Po); positioning of an opaque filter pierced with at least two holes in the optical path; execution of a number of image acquisition steps in which the controlling alignment parameters are known; determination for each light point and for each alignment process a list of distances between the images and their point light sources; calculation for each light point and alignment process an evolution function and from all the evolution functions and alignment processes determine an optimum alignment in which the distance between the point images is a minimum.
