Precise pointing alignment of optical probes

Abstract From the Canadian patent

Two camera models are each viewed by an optical probe such that each optical probe views its respective model with the same perspective. To this end both proves are pointed towards a desired point on their respective model boards. A light beam, characterized by a particular light signature. Is emitted from the desired point on each board and passed to a detector by the probe associated with that board. Detection is on an array of photosensitive elements arranged such that the X-Y coordinates of the point of impingement of the beam on the array may be determined. The location of each light beam on each detector array is correlated. The pointing of the probes is then adjusted such that when …
