A depth obtaining component includes a laser driver array and a laser array. The laser array includes a plurality of lasers. The laser driver array includes one or more control units, and each control unit is configured to control selection of one or more lasers in the laser array. The one or more control units are disposed in a charge loop of the laser driver array. A laser corresponding to the control unit can be flexibly selected based on a first switch module and a capacitive module in the control unit. In this way, scanning laser emission of the laser array can be implemented based on the laser drive circuit, no scanning device such as a micro electro mechanical systems mirror needs to be additionally disposed, and circuit support can be provided for implementing a small-sized, power-efficient, and cost-effective optical transmit end.
