ToF sensor, this technology is a kind of two-way ranging method. The basic principle is to continuously send light pulses to the target, and then use the sensor to receive the light returned from the object. There is a time difference in this process, so as to calculate the transmitter and the target. Measure the distance between objects. The whole principle is actually similar to radar. A complete ToF system should include components such as a transmitter, an object under test, a receiver, and a control chip. The transmitter mainly sends the optical fiber to the measured object, which is generally invisible infrared light. The measured object reflects the received light, the receiver receives the reflected light, and the chip controls the transmission of the entire light and calculates the time difference between the transmission and reception of the light.The tof technology basically has three major uses on mobile phones, namely photography, security, and entertainment. The previous article introduced that ToF components detect distance by emitting invisible light.The light emitter here is like laser focusing, which can improve focusing speed and accuracy. On the other hand, ToF is like a more in-place depth-of-field lens that can Provide a more natural bokeh effect.
