DOI: 10.1016/j.ijleo.2021.167568

Abstract: Abstract For any optical encryption and decryption systems, security is the major concern. In this paper, security of time varying nonlinear term embedded double random phase encoding (DRPE) scheme is enhanced by using Modified Gerchberg… read more here.

recommendations! Published in 2019 at "Optics Communications"

DOI: 10.1016/j.optcom.2018.09.076

Abstract: Abstract Holographic laser beam shaping using a spatial light modulator can provide flexible adaptation of the intensity profile. However, speckle noise exists in the shaped beams, which reduces the beam quality seriously. In this paper,… read more here.

DOI: 10.1364/oe.27.002184

Abstract: We demonstrate fast and efficient neutral atom rearrangements in an optical tweezer-trap array, using an enhanced hologram generation algorithm. The conventional Gerchberg-Saxton (GS) algorithm is modified to include zero-padding hologram expansion for optical tweezer sharpness,… read more here.

DOI: 10.3390/mi14051014

Abstract: It is very important for holographic optical tweezers (OTs) to develop high-quality phase holograms through calculation by using some computer algorithms, and one of the most commonly used algorithms is the Gerchberg–Saxton (GS) algorithm. An… read more here.
