SLM aided noninvasive imaging through thin scattering layers
Saswata Mukherjee, A. Vijayakumar, Joseph Rosen
We propose and demonstrate a new imaging technique to noninvasively see through scattering layers with the aid of a spatial light modulator (SLM). A relay system projects the incoh…
Binary square axicon with chiral focusing properties for optical trapping
Balasubramani Vinoth, Anand Vijayakumar, Mani Ratnam Rai +4
We introduce a novel phase-only diffractive optical element called chiral binary square axicon (CBSA). The CBSA is designed by linearly rotating the square half-period zones of the…
Structured light by discrete-phase orbital angular momentum holograms
A. Vijayakumar, Carmelo Rosales-Guzman, Mani Ratnam Rai Joseph Rosen +3
Structured light has been created by a myriad of near- and far-field techniques and has found both classical and quantum applications. In the case of orbital angular momentum (OAM)…
Incoherent digital holograms acquired by interferenceless coded aperture correlation holography system without refractive lenses
Manoj Kumar, A. Vijayakumar, Joseph Rosen
We present a lensless, interferenceless incoherent digital holography technique based on the principle of coded aperture correlation holography. The acquired digital hologram by th…
