Abstract: A time-of-flight (ToF) module includes a light source, a driver module, and a light sensor. The driver module includes electrical circuitry configured to selectively drive the light source to emit pulsed illumination light. The light sensor is configured to sense returning light reflected from a target. At least one of the light source, driver module, and light sensor is stacked on another to reduce a footprint of the ToF module.
