METHOD AND DEVICE FOR OPTICALLY TRANSPARENT MICRO-OBJECTS SPECTRAL DIGITAL HOLOGRAPHIC IMAGES RECORDING Russian patent published in 2016 - IPC G01N21/45 G01B9/23 G03H1/26 

FIELD: information technology.

SUBSTANCE: method of spectral digital holographic images producing, implemented by device, consists in formation of collimated broadband light beam, its selective diffraction in acousto-optical filter, its division into two beams, passing of one of them through analyzed object. Then, performing convergence of two beams into one with alignment of wave fronts propagation direction. Providing optical radiation selective diffraction in second acousto-optical filter and recording of diffracted beam by radiation matrix receiver.

EFFECT: technical result consists in provision of multiple narrow spectral recording bands using single broadband light source, elimination of spatial-spectral distortions of images for their precision spatial alignment, reduced sensitivity to external flares, higher stability of device operation and higher spectral contrast.
