Description：

The VL53L1 is a laser-ranging ToF sensor. It covers applications requiring long distance ranging up to 800 cm (ranging mode), multizone ranging (scanning mode), and low-power (autonomous mode). A comprehensive application note (AN5573) provides technical details on the programming interface including its bare driver. The API (application programming interface) enables the device to be

controlled and managed in these three modes, to meet the requirements of all applications.With patented algorithms and ingenious module construction, the VL53L1 is also able to detect different objects within the FoV (field of view). Its depth information (histogram) is at 60 Hz.Scene browsing and multizone detection are now possible with the VL53L1, thanks to a software customizable detection array. This provides a quicker “touch-to-focus”, or minidepth map use cases.

Application：

• Laser assisted autofocus (AF): enhances the camera AF system speed and robustness, especially in difficult scenes (low light and low contrast). Ideal companion for PDAF sensors.

• Video focus tracking assistance at 60 Hz

• Scene understanding with multiobject detection: “choose the focus point”

• Dual camera stereoscopy and 3D depth assistance thanks to multizone measurements

• Presence detection (autonomous timed mode), typically to lock/unlock and power on/off devices like notebooks, tablets, or white goods
