We propose designs of pupil-domain optical diffusers for a snapshot spectral imaging system using binary-phase encoding. The suggested designs enable the creation of point-spread functions with defined optical response, having profiles that are depen

We propose a snapshot spectral imaging method for the visible spectral range using two digital cameras placed side-by-side: a regular red–green–blue (RGB) camera and a monochromatic camera equipped with a dispersive diffractive diffuser placed at

Snapshot spectral imaging was experimentally demonstrated using a monochromatic camera with binary diffuser, and an RGB camera. The diffuser sets a wavelength-dependent point- spread function which enables reconstruction of 1944x256x27 spectral cubes

In this letter, we report on the excitation of low order Laguerre–Gaussian mode groups with a common propagation constant in a multimode gradient index optical fiber. Enabling generic space-division multiplexer was based on a key multichannel diffr

We experimentally demonstrate a compact optical spectrometer with a resolution of up to $\sim 0.1$ nm suitable for spectral line measurements of laser diodes. This spectrometer is based on a transmission, 4-mm in diameter, and 0.14-NA off-axis binary

Capabilities of beam shaping with diffractive optics are substantially improved by a concept of crossed zones. We generalized the map transformation design of beam shapers by additional set of diffractive zone borders orthogonal to phase isolines. Ap
