AI Technical Summary

Problems solved by technology

The traditional photoelectric receiving device for laser energy transmission only has the function of photoelectric conversion, which converts the laser light irradiated on the battery panel into electrical energy, and cannot directly measure the intensity distribution of the received laser spot. Therefore, it is usually necessary to use other methods to measure the far field Spatio-temporal distribution of spot intensity, which brings unnecessary difficulties to the application of laser wireless energy transfer system
