Mainly from long-wavelength human eye safety ranging discussed and studied the 1nGaAs avalanche photodiode preamplifier circuit design and parameters of the preamplifier and photodetector components hybrid integration. The application and design of the laser receiver composed of InGaAs avalanche photodiodes are discussed from the application of laser ranging. The relationship between the photoelectric characteristics and the bias voltage of the InGaAs avalanche photodiode was tested from the perspective of ranging, so as to understand the difference between the optoelectronic properties of the device and the silicon avalanche diode so as to provide a reference for the better application of the InGaAs avalanche photodiode And based on. Developed InGaAs avalanche photodiode detector components and receivers in the laser range finder ranging applications, the laser energy of 7 milli Joule distance from the focus on distance, the initial meet the requirements.
