Abstract

一种深度获取组件及电子设备，包括激光器驱动阵列(002)和激光器阵列(003)；激光器阵列(003)中包括多个激光器(162)；激光器驱动阵列(002)包括一个或多个控制单元(160)，各控制单元(160)用于控制激光器阵列(003)中的一个或多个激光器(162)的选择；一个或多个控制单元(160)设置在激光器驱动阵列(002)的充电回路中，基于控制单元(160)中的第一开关模块(1601)、容性模块(1602)可以灵活的实现对控制单元(160)对应的激光器(162)的灵活选择，从而使得基于激光器驱动电路可以实现对激光器阵列(003)的扫描激光发射，不需要额外设置转镜等扫描设备，从而可以为实现小尺寸、小功耗、低成本的光发射端提供电路支持。
