【 摘 要 】

The expensive photosensors of scientific cameras are commonly used in the wide variety of research fields. However, photosensors that are implemented in DSLR cameras are seen to be an appropriate substitution in order to decrease price/quality ratio or even receive additional features. In this article different scientific applications of DSLR cameras' photosensors with Bayer filter as well as calibration methods of its spectral characteristics are discussed. The approach, based on determination of latter and usage of its features, is shown to increase SNR of the color reconstructed images in digital holography.
