Abstract
A laser diode illuminator for single photon detection (SPAD) based pulsed time-of-flight 3-D range imaging is presented. The illuminator supports the block-based illumination scheme. It consists of a 16-element custom designed common anode quantum-well (QW) laser diode bar working in the enhanced gain switching regime and lasing at ~810nm. The laser diode elements are separately addressable and driven with GaN drivers producing 5...10A/~2ns current pulses from a supply voltage of 90V. Cylindrical optics is used to produce a total illumination field-of-view of 40ºx10º (FWHM) in 16 separately addressable blocks. With a laser pulsing frequency of 256kHz and laser pulse energy of ~8.5nJ, the average optical illumination power of the transmitter is 2.2mW
