Laser sources have been promised for many years to be better light sources as compared to
traditional lamps or light-emitting diodes (LEDs) for projectors, which enable projectors …

无线通信中的频段资源已经十分紧张, 在6G 复杂的通信环境下, 传统的无线通信也难以达到全面
的高速覆盖. 可见光通信作为一种利用400~ 800 THz 无须授权频段的高速通信技术, 将在6G …

We propose and demonstrate a speckle reduction technique in a laser diode projection
system. By modulating the drive current of the laser diode continuously, we manage to …

We report on the implementation of a current drive modulation circuitry that is effective in
suppressing speckle noise for laser diodes. The drive circuit allows for operating the laser …

Illumination for line-scan machine vision systems is required to produce a highly asymmetric
elliptical beam pattern, to maximize system speed and accuracy. The use of LED emitters …

Benefiting from the high modulation bandwidth (BW), low energy consumption and excellent
optical performance, lead halide perovskite has attracted wide attention in visible light …

Based on visible light communication technology which has been a research hotspot in the
field of communication, this paper reviews the background of visible light communication …

A transparent optical fingerprint capture system based on grating couplers was proposed
and demonstrated. Metallic gratings were used as high efficiency input/output couplers to …

A backlight unit is constructed by laying out an optical fiber on a two-dimensional plane and
letting the light leak out in a controlled manner. In experiment, we formed multiple grooves …
