Solid‐state lighting is advancing toward higher power, higher brightness, and smaller size to
cope with the market competitiveness, and laser‐driven solid‐state lighting technology is …

Silica aerogels with accurate building‐block control are realized by adjusting the surfactant
concentration during the synthesis process. The resulting silica‐aerogel monolith with …

Speckle is the main obstacle for the use of laser light sources in projection technology. This
paper focuses on speckle suppression by the reduction of temporal coherence which is …

In this study, a miniaturized full-color holographic reconstruction system that uses a single
spatial light modulator to achieve full-color image reconstruction was developed. The …

Our study proposes a novel method for obtaining speckle-free homogeneous illumination
using a combination of a multi-retarder plate, a microlens array, a Fourier lens, and a …

Speckle, due to the interference of coherent light having random phases, can seriously
degrade image quality in a laser based projection system. The speckle is even worse when …

ABSTRACT A liquid crystal (LC) with negative dielectric anisotropy called N-(4-
Methoxybenzylidene)-4-Butylaniline (MBBA) doped with the ionic agent …

We study laser speckle reduction by light pipes, and we propose a new method to improve
its efficiency. Proof-of-concept refractive optical elements (ROEs) with a staircase-like …

In computer-generated holography, spatial light modulators are predominantly used for
image reconstruction. However, the quality of the reconstructed images is often …

In this paper, a solution for speckle reduction using phase plate array (PPA) and lens array
(LA) in a motionless way is proposed. The specially designed PPA is composed of sub …
