激光唱机
compact disc player

J一guong chongJ-激光唱机(eompaet disc player)重放记录在徽光唱片上的数字式音频信号的设备，又称激光式数字音频唱机、CD唱机。激光唱盘是采用激光刻录、激光拾取音频信号的一种数字唱盘，又称激光式数字音频唱盘、CD唱盘. 激光唱机由信号拾取器、射频(RF)放大器、解调电路、信号处理电路、数模转换器和低颇放大电路等部分组成(见图). 信号拾取器是由半导体激光器(拾音头)、光学系统、检波器等组成.半导体激光器发出的激光束经瞄准镜头成平行光线，再经过棱镜、1/4波长板到达唱盘，反射回来后集中在检波器上.检波器使用发光二极管，经过检波器所得的信号有主信号.即射频(RF)信号，还有使光束聚集正确的聚焦信号和使循迹正确的循迹信号。射频信号经射频放大器后，一部分输人聚焦、循迹伺服电路，这两个伺服电路的输出，可以控制信号拾取器的驱动器;另一部分进人解调电路，在解调电路音狡愉出 ┌───┐ ┌───┐ │滋光 │ │存储器│ │唱盘 │ │ │ └┬─┬┘ └───┘ │口│ ┌──┐ ┌┴─┴┐┌────┐┌──┐┌────┐ │电机│ │信号 ││热 ││蓄念││{，。;.!│┌───┐│ │ │拾取器││ ││ │├────┤│低孩 │└──┘ └───┘└────┘└──┘│遏笔菇 ││故大器│ └────┘└───┘ ┌────┐ ┌────┐ │滚焦f司 │ │控制 │ │服电路 │ │电路 │ └────┘ └────┘ ┌───┐ │搜转控│ ┌────┐ │制电路│ │表示 │ │ │ │口电路 │ └───┘ └────┘ 激光唱机工作原理框图中，首先将输人信号以一定基准作高、低判定，以变换成完全的矩形波，同时利用锁相环电路将同步信号分离。
