1．激光应用于射击训练一般是靠靶面上的光敏元件来检测击中与否。若要显示出射中靶面的具体环区，则需要由很多光电转换元件组成的列阵。采用这里所介绍的全息模拟靶可以克服上述缺点。对于六环区军用胸环靶的每一个环区只需一个光电元件接受，由数码管直接显示射中的环数。rrrrrrrrn 1. Laser application to shooting training is generally based on the photosensitive element on the target surface to detect hit or not. To show the specific ring region of the target being shot out, an array of many photoelectric conversion elements is needed. The use of the holographic simulation target described here can overcome the above drawbacks. For the six Central District military chest ring target ring area only one optoelectronic components to accept the digital tube directly shows the number of shots. r r r r r r r r n
