简述了激光核聚变试验中遥控靶位用的四频道电视系统。该系统确保直径为50～800微米的球形靶定位到真空靶室空间的最佳点,且允许在三维空间坐标范围内以±5微米精度控制靶位。靶象以≤500的总倍率在电视接收屏上监视。 The four-channel television system for remote control of target in laser fusion test is briefly introduced. The system ensures that spherical targets 50 to 800 microns in diameter are positioned to the sweet spot of the vacuum target chamber space and allows the target to be controlled with a precision of ± 5 microns within three-dimensional spatial coordinates. The target is monitored on the TV reception screen at a total magnification of ≤500.
