Especially for displays, visible-wavelength lasers are in high demand for a wide range of
applications. Active research and development have been devoted to laser-based displays …

Laser speckle contrast imaging (LSCI) is applied in various biomedical applications for full-
field characterization of blood flow and tissue perfusion. The accuracy of the contrast …

We report on a novel speckle reduction scheme using microlens arrays as screen material
for application in laser-based projection systems. The scheme is based on properly …

Abstract 1 A new method is reported for determining the concentration of dimethyl
methylphosphonate (DMMP) vapor based on the capture of laser speckles from a liquid …

A technique based on the superposition of two uncorrelated speckle patterns and speckle
contrast measurement is proposed and demonstrated to track the polarization rotation of an …

Acetone, a common volatile organic compound (VOC), poses health risks even at low
concentrations. Current acetone sensors are costly and require specialized equipment and …

This study explores the application of optical fiber lasers in display systems by integrating a
P r3^+-doped green all-fiber laser into a laser projection display system. As a control group …

In high lumen laser projectors, it is required to use laser diodes coupled to multi-mode fibers
(MMFs) to obtain a high power illumination module. In this paper, we have fabricated an …

An electroactive despeckle diffuser (EADSD) is demonstrated using a polymer dispersed
liquid crystal (PDLC) in-plane switched by two pairs of interdigitated electrodes whose …

We propose a flexible and lightweight laser speckle noise suppression module based on the
combination of a multimode fiber (MMF) and a macro fiber composite (MFC). The …
