Description

The VL53L5CP is a state of the art, ToF (Time-of-Flight), laser-ranging sensor, enhancing ST's FlightSense family.

It is housed in a miniature and reflowable package, which integrates a SPAD array, physical infrared filters,

and DOEs. Consequently, this sensor achieves outstanding ranging performances, in various ambient lighting

conditions, with a range of cover glass options.

The use of DOEs above the VCSEL allows a wide square FoV (61°) to be projected onto the scene. A receiver

lens focuses the reflection of this light onto a SPAD array.

Unlike conventional IR sensors, the VL53L5CP uses ST's latest generation, direct ToF technology, which

allows absolute distance measurement whatever the target color and reflectance. This technology also provides

accurate ranging up to 400 cm. In addition, it enables the sensor to work at fast speeds (60 Hz). All this makes

the VL53L5CP the fastest, 64-point, miniature ToF sensor on the market.

With patented algorithms and ingenious module construction, the VL53L5CP can also detect different objects

within the FoV. Depth information is possible at 60 Hz.

Additionally, the VL53L5CP can browse scenes and detect multizones. This is due to a software customizable

detection array, which detects low power and fast human presence, or a mini depth map.

This device is ideal for multizone ranging, multi-object detection, and scene understanding. It controls wake-up

and sleep functions. Consequently, it is particularly suited for human presence detection in front of a PC or a

control panel. Special algorithms are available to distinguish humans from inanimate objects. The device enables

countless applications, including reading distance monitoring and gesture.
