Keysight Application Note :: LIV Test of VCSEL for 3D Sensing with Keysight B2900A Precision Source/Measure Unit.
The integration of 3D sensing and imaging capabilities into various applications such as consumer electronics, medical, industrial and commercial robotics, automotive, aerospace and defense have driven the growth of the global 3D sensing and imaging market. For consumer electronics applications like smartphones, tablets, and laptops, the accelerating growth is phenomenal.
The light-current-voltage (LIV) sweep test is a fundamental measurement to determine the operating characteristics of optical devices such as laser diodes (LDs) and Vertical Cavity Surface Emitting Lasers (VCSELs).
