We used the mirror­shadow method for the diagnostics of stressed­strained state of shaped sections of metal structures. It was found that in the course of implementation of this method there may occur an error that is caused by misalignment of meas

Publikováno v: Thirteenth International Conference on Correlation Optics.

In this article, the limiting characteristics of a digital optoelectronic processor are explored. The limits are defined by diffraction effects and a matrix structure of the devices for input and output of optical signals. The purpose of a present re

The diffraction limit of an optical spectrum analyzer

Autor: G. S. Tymchik, Valentin G. Kolobrodov, Mykyta S. Kolobrodov

Publikováno v: SPIE Proceedings.

This article examines a systematic error that occurs in optical spectrum analyzers and is caused by Fresnel approximation. The aim of the article is to determine acceptable errors of spatial frequency measurement in signal spectrum. The systematic er
