How accurate is the long-distance laser ranging sensor?
Laser ranging is a commonly used precise ranging technology, which is widely used in the field of metaverse, interactive entertainment and industrial automation, and can meet measurement requirements such as distance measurement, area measurement, volume measurement, and height tracking. There are three types of laser ranging: one-dimensional, two-dimensional, and three-dimensional. Through the wireless communication function, two-dimensional or three-dimensional models can be obtained directly in the application of the host computer (PC terminal or mobile phone). If the hardware circuit is well designed, coupled with the laser ranging algorithm, the distance value with an error in the millimeter level can be measured. There are many ways of laser ranging. The phase method in the time-of-flight (ToF) method is used in this scheme. The advantage is that the accuracy is high, and the accuracy can reach the millimeter level. However, the phase method requires more complicated calculations, and asynchronous acquisition synchronization, difference frequency phase measurement, Fourier transform, distance synthesis, etc. are used in the measurement process. This article organizes the above complex operating principles into this solution, which provides customers with direct reference and use, so as to effectively reduce the cycle of product development for customers.
