What are the components of tof sensor?

Tof sensor have become an indispensable part of many flagship smartphones. How does tof sensor measure the distance of an object? What are the components of tof sensor?

Tof sensor uses infrared light. After the light is reflected from the object back to the sensor, the distance between the sensor and the measuring object can be calculated according to the time difference between the emission and reflection of the light. tof sensor is also called "depth camera" or ToF camera.

Tof sensor is composed of two parts: the first part is a diode that emits infrared light, and the second part is a special photosensitive matrix. The sensor can measure the time reflected from the object to the order of nanoseconds. In addition, the ToF sensor has an important feature that makes it a 3D sensor. That's because the ToF sensor can not only accurately calculate the distance between a single object and the sensor, use the difference in laser return time and wavelength, but also perform accurate digital three-dimensional (3D) characterization of the target, and intuitively draw the various features of the target.
