Offset Interference of Laser TV

激光扫描显示系统中散斑研究

“…In this display, different pixels are written at different time, so there is no possibility of interference between pixels. This is an advantage and simplification over displays in which laser illuminates a one-or two-dimensional (2D) spatial light modulator [SLM, such as digital light processing (DLP) or liquid crystal on silicon (LCOS)], leading to pixel-to-pixel interference effects [7] . A difficulty of beam scanning is that each pixel is illuminated for a very short time when the entire image is being written.…”
