In mobile devices, 3D Sensing is one of the latest functions. This can be achieved by Time-of-Flight (ToF) method or structured light method. Infrared structure light projector is composed of a laser light source, a collimated lens and a diffractive optics element (DOE). The light sources can be divided into two common types: the Edge Emitting Laser (EEL) or the Patterned Vertical Cavity Semiconductor Emission Laser Array (patterned-VCSEL array). In this paper, we will compare these two optical structures, EEL with high density dots pattern and patterned-VCSEL array with several impulse dots.
