Abstract:
Remote measurements of geometric dimensions of engineering products using electromagnetic waves of the optical range are classified into coherent (diffraction, interference, speckle structures) and incoherent; with imaging or without imaging; with filtration at optical frequencies or after transformation into an electrical signal. Coherent optical systems are the most universally applicable and allow parallel processing of two-dimensional fields with the speed of light propagation, but high requirements to the quality of the hardware components and propagation medium make the use of coherent circuits dependent on the development of integrated optics. Therefore, incoherent installations are used more widely in production conditions, although the laser can also serve as a light source, especially in the situations where spectral selection, high peak powers, and low beam divergence
are necessary. The main consumers of optoelectronic measuring instruments, including laser measuring instruments, are the production enterprises with 100% output control [1], i.e. aircraft and aerospace manufacturers.
