摘要
激光测距传感器可以测量激光脉冲飞行时间来获得传感器和探测目标之间距离。设计的脉冲激光测距传感器采用Spl pl90半导体激光器,PerkinElmer C30737型APD作为接收的光电转换器,Msp430f449单片机作为系统控制核心。为了提高激光飞行时间间隔的测量精度,采用了一种专用的时间数字转换芯片(TDC-GP2),设计了时间间隔测量模块,采用延迟线插入法技术,测试分辨率可高达65 ps.该传感器功耗低,测量精度高。
Pulsed of time-of-flight laser range sensor measure the distance between sensor and target by calculate the flight time of laser. Pulsed laser range sensor adopt Sp1 pl90 laser diode as laser emitter, PerkinElmer C30737 APD was used in photoe-lectric detection circuit, MSP430f449 MCU as the core of control system, in order to increase measurement accuracy, use a special time-digital-converter chip to design a high time interval measure module which adopts the delay line interpolation method, and the maximum time resolution is 65 ps. The sensor has lower power consumption and high precision.
