Measuring NIR Sources for Safe and Accurate 3D Sensing
Jan 16, 2019 — 3D sensing with NIR wavelengths has taken off in the past several years, with use in such applications as facial and gesture recognition, eye tracking, and automotive vision systems such as lidar. The market for these optical sensing systems is projected to see a 22.7 to 24 percent compound annual growth rate, reaching as high as $3.8 billion in total revenues by 20271,2. NIR wavelengths range from 700 to 1500 nm, and NIR light sources can be used for multiple applications. For example, NIR
