Annotation
А simple, compact sensor of spatial coherence based on а Y-type fiber directional coupler. The signal at the sensor output is created as а result of interference of the light beams captured Ьу the lightguide cores. The sensor permits spatial separation of the investigated plane of the beam and the recording apparatus, the use of electronic processing of the signal, and measurement of the radius of curvature of the laser-beam wavefronts.
