在汽车工业中，光电子学可以满足汽车的安全和便利的要求。此类装置之一是自适应巡航控制（ACC）系统。该系统用激光束或雷达监视一辆车与前一辆车的距离和速度，从而使车加速或减速，使两车保持一定距离。系统的作用很象普通巡航控制系统，使车以驾驶员设定的固定速度行驶。但 In the automotive industry, optoelectronics meets the requirements of automotive safety and convenience. One such device is the Adaptive Cruise Control (ACC) system. The system uses a laser beam or radar to monitor the distance and speed of a car from the previous car, thereby accelerating or decelerating the car to keep the car at a distance. The system functions much like a normal cruise control system, driving the car at a fixed speed set by the driver. but
