摘要

In the paper, a design scheme of driving circuit and collimating optical system used for 3D (three-dimensional) imaging device has been proposed. The driving circuit based on power MOSFET for high-power pulsed laser diode has the characteristics of short pulse-width and high output current. According to semiconductor laser's far field divergence characteristic, the aspheric collimation part has been designed by using optical design software ZEMAX. Far field beam tracing and collimation results are simulated. The laser driver's output current and pulse width are about 144A and 13.9ns respectively. The RMS of divergent angle of simulation in ZEMAX is _0.318mrad and the spot is more uniform.
