Many applications require sensing the presence or distance of an object without touching the actual object. This need for proximity sensing has prompted numerous competing solutions, including optical time-of-flight (ToF) sensors. ToF sensors are compact and easy to install, it with excellent accuracy for a wide range of applications. ToF sensor is Perfect choose for proximity sensing solutions.
The list of products that use proximity sensing includes camera autofocus systems, robots and drones, various bathroom fixtures, and access sensors for automatic doors. The list of such products is constantly expanding. Competing proximity-sensing technologies started with simple infrared and ultrasonic sensors, and gradually progressed to more complex sensor systems, such as stereoscopic video cameras using neural networks.
An alternative proximity sensing solution is the ToF sensor. They measure the distance to a target object by measuring the round-trip time for photons emitted from the sensor to the object and reflected back. A new generation of highly integrated, low-cost ToF sensors allows us to bring highly accurate contactless sensing technology into low-cost designs.
