6604E/16-200 FORCE信标激光发射模块为激光通讯链路的建立供给用来对准的信标光,为了便当激光发射和接收部分的对准,要求信标光的光束具有较大的柬散角和较高的输出功率。 驱动部分是由基准电压源发作基准电压,然后将激光器(LD)输出电流转换为电压进行取样,通过反响环路与基准电压进行比较,运用反响量来控制驱动电流大小,使供给激光器电流安稳,然后结束恒流控制;将检测二极管(PD)电流大小反响给驱动,结束功率自动控制;温度控制部分是由内部热敏电阻通过电桥电路扩展供给后续的TEC电路,运用TEC处理芯片结束温度监测和控制。此外由脉冲信号源生成必定周期的时钟频率信号,作为发射模块控制频率,然后抵达结束脉冲输出。
6604E/16-200 FORCE激光器驱动电路规划,激光器驱动电路如图2所示,电路规划中,选用运算扩展器和自动增益控制电路。在该图中电路分红两个部分,图中的上半部分电路为脉冲驱动,下半部分电路为自动增益控制电压电路。
6604E/16-200 FORCE在上半部分电路中,P1为SMA接头,选用50 Ω阻抗匹配将脉冲控制信号接入作为调制激光器驱动的调制信号,通过后续比较器和驱动电路结束开关控制。VD7为稳压二极管供给安稳电压,通过调整滑动变阻器来结束比较器负输入端参看电压的设定。U8为MAX953集成芯片,内部集成了比较器和扩展器。在该部分规划中,通过比较器结束脉冲控制电压和参看电压的比较,将比较信号送入后续由MAX953芯片内的扩展器构成的电压随从器正向输入端。在电压随从器的正向输入端外接参看电压的上拉电阻相接,比较器输出开关信号来控制电压随从器正向输入端的电压大小结束开关功用,以便结束后续供给场效应管VQ10的打开和导通,然后结束脉冲开光信号的整体控制。通过反响电压控制电压随从器的上拉电压抵达电流安稳驱动的目的。
鄙人半部分电路中,将恒电流反响或恒功率反响控制信号通过运放扩展,其间运放仍选用U10中的内部扩展器,将该运放作为电压随从器,输出信号进入运放 U11A的正向输入端结束扩展。U11B为运放减法电路,将上级扩展输出信号与参看电压进行比较输出,VD10为稳压二极管供给安稳电压,调整滑动变阻器 R77和R70构成的分压电路来结束比较器负输入端参看电压的设定。在该部分电路规划中,自动增益控制电路中的扩展器选取带宽较窄、转换速度不能过快的扩展器为宜。由于调制频率为kHz数量级,因而带宽过大会有很大的噪声烦扰,为了使自动增益控制电压坚持安稳,有必要使该电压转换缓慢,所以选取改动速度较为缓慢的运算扩展器。R61为恒电流方式中的采样电阻,即它将LD的电流转换为电压信号,通过反响回路作为恒流控制信号,将该小信号扩展供给后续反响回路。 由于LD的输出功率与驱动电流有关,所以驱动电流的安稳性是抉择LD的输出光功率安稳与否的一个关键因素。
