Description

Specially designed for applications requiring an ultrawide FoV, the VL53L7CX Time-of-Flight sensor offers a 90°

diagonal FoV. Based on ST's FlightSense technology, the VL53L7CX incorporates an efficient metasurface lens

(DOE) placed on the laser emitter enabling the projection of a 60° x 60° square FoV onto the scene.

Its multizone capability provides a matrix of 8x8 zones (64 zones) and can work at fast speeds (60 Hz) up to

350 cm.

Thanks to the autonomous mode with programmable distance threshold combined to the ultrawide FoV, the

VL53L7CX is perfect for any application requiring low-power user detection. ST's patented algorithms and

innovative module construction allow the VL53L7CX to detect, in each zone, multiple objects within the FoV

with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 60 cm.

Derived from the VL53L5CX, the pinouts and drivers of both sensors are compatible, which ensures a simple

migration from one sensor to the other.

Like all Time-of-Flight (ToF) sensors based on ST's FlightSense technology, the VL53L7CX records, in each zone,

an absolute distance regardless of the target color and reflectance.

Housed in a miniature reflowable package that integrates a SPAD array, the VL53L7CX achieves the best ranging

performance in various ambient lighting conditions, and for a wide range of cover glass materials.

All of ST's ToF sensors integrate a VCSEL that emits a fully invisible 940 nm IR light, which is totally safe for the

eyes (Class 1 certification).

The VL53L7CX is the perfect sensor for any application requiring ultrawide FoV like robotics, smart speakers,

video projectors, content management. The combination of the multizone capability and the 90° FoV can enhance

new use-cases like gesture recognition, SLAM for robotics, and low power system activation for smart building.

Application

• Ultra wide FoV and multizone scanning allows content management (load in

trucks, tanks, waste bins)

• Applications requiring ultrawide FoV, like smart speakers, vacuum cleaners

(three sensors can cover 180° x 60° FoV)

• Gesture recognition with wide field of detection

• Devices requiring ultrawide FoV for user detection to wake-up devices (smart

buildings, smart lighting)

• Keystone correction for video projectors

• Robotics applications (SLAM, wall tracking, small object detection, cliff

prediction, floor type recognition)

• Augmented reality/virtual reality (AR/VR) enhancement. Dual camera

stereoscopy and 3D depth assistance thanks to multizone distance

measurement

• IoT (user and object detection)

• Video focus tracking. 60 Hz ranging allows optimization of continuous focus
