| Description | A patent application was presented for an invention whose principal objective is the provision of an improved alignment device for observing the degree of coalignment of a pair of objects. The device includes a beamsplitter to be interposed between a pair of objects for observing the degree of coalignment. Light from one of the objects is reflected from the beamsplitter into a retroreflector which reflects the light back through the beamsplitter into an imaging system. Light from the other object is reflected from the beamsplitter into the same imaging system. The amount of displacement of the two images is inversely related to the degree of coalignment of the two objects. The optical alignment device is useful for aligning a mirror with an object, two objects or two mirrors. |
