The improvement of bearing characteristics of a matrix photodetector device when observing point objects by equipping their photosensitive elements with microlenses is nonlinear in nature. The maximum increase in the proportion of a detected signal is ~20 %, while the expected average is 10 %. The greatest realization of microlenses potential can be achieved with prior information about the direction of movement of observed objects.

This work is devoted to the study of experimental samples of superluminescent radiation for interference devices and systems operating in low-coherent light by spectral analysis. In optical instrumentation, great attention is paid to superluminescent LEDs, because they are widely used in low-coherence interferometry due to their technical characteristics. The use of the spectral method to identify the maximum wavelength of radiation, the width of the spectrum is important, since these parameters determine the length of coherence, therefore, this work is relevant and promising. The purpose and task of the study is set. The functional diagram of the measuring unit and the monochromator unit are given. Graphical dependences of the relative spectral sensitivity of experimental samples on different heterostructures are obtained and the coherence length for each light source is calculated.
