A technique of measuring spectral characteristics of detector arrays in amateur and professional photocameras and their application for problems of digital holography

Abstract

The possibility of using commercial digital cameras that support image saving in the RAW format in scientific applications for measuring spatial intensity distributions in different ranges of the visible spectrum is considered. Spectral characteristics of photo sensors were measured for three digital cameras: Canon EOS 1000D, Nikon D50, and Nikon D90. Ways of applying spectral characteristics in problems of improving the quality of multicolor digital holograms are considered. © 2013 Pleiades Publishing, Ltd.
