Time-of-Flight (ToF) Ranging Technology

The Time-of-Flight (ToF) ranging technology is a literal translation of "Time of Flight", abbreviated as ToF. Its basic principle is to continuously emit light pulses (usually invisible light) to the observed object, then receive the light pulses reflected back from the object, and calculate the distance between the measured object and the sensor by detecting the flight (round-trip) time of the light pulses.
Advanced Treatment

3D ranging refers to the ability to detect a large number of pixels; after calculation, the output distance value is called depth.
Algorithm Application

After the customer's backend processing chip receives the depth data, it converts it into a 3D point cloud. Using different algorithms, various applications (such as drone altitude hold) can be realized.
VCSEL Surface Laser Light Source

VCSEL is a type of laser. As a surface-emitting device, it is similar to a flashlight and typically operates in the infrared band, which is invisible to the human eye. A dedicated VCSEL driver chip is required for its operation.

ISP Chip

The ISP Chip receives the raw data generated by the ToF Sensor and calculates depth and other information in real time by means of an on-chip low-power, high-performance computing engine. Compared with the traditional solution that relies on external computing power for depth calculation, it simplifies ToF depth computation and significantly reduces the difficulty of user development. Meanwhile, the ISP Chip has a built-in ARM Cortex-M3 core, providing flexibility for implementing customized algorithms for customers.
