CALIBRATION OF ACCURATE ELECTRO-OPTICAL RANGE FINDERS BY THE MEANS OF LASER-DOPPLER INTERFEROMETER

Abstract

The precision of short range electro-optical rangefinders has been improved significantly. This fact made it applicable to perform microgeodetic measurements in mechanical engineering, requiring extreme high precision. But there is a strong need for regular calibration of these instruments - possibly by applications of even more precise laser-Doppler inter-ferometers - those the paper deals with.
