Device for marking picture elements in photograms by means of laser beams

To reduce beam losses and adjustment complexity, a laser with two beams emitted diametrically with respect to one another is used in connection with a stereoscopic viewing system, which is achieved by coating the resonator reflector with equal reflection layers (R APPROX 60 ... 90%). The invention c...

Zusammenfassung:To reduce beam losses and adjustment complexity, a laser with two beams emitted diametrically with respect to one another is used in connection with a stereoscopic viewing system, which is achieved by coating the resonator reflector with equal reflection layers (R APPROX 60 ... 90%). The invention can be used in the field of analytical photogrammetry for point marking and transmission.
