摘要 | PURPOSE:To form an inexpensive laser driving circuit having high accuracy by lowering the power source voltage of a gate circuit until the output of an amplifier follows up said voltage. CONSTITUTION:A circuit 507 for regulating photodetector output is made into such configuration consisting of a 2kOMEGA variable resistor VR2 and fixed resistors of R16:1kOMEGA, R17:2kOMEGA, and R30:100OMEGA. A jumper pattern exists in the resistors R16, R17 and cut points CP1-CP3 are provided. Nothing is done up to 100-2,100OMEGA series resistance RPD and CP1 is cut before 110-3,100OMEGA. The circuit is so constituted as to cut CP2 before 2,100-4,100OMEGA and to cut CP3 before 3,100-5,100OMEGA. The accuracy of the regulation is enhanced and such inexpensive configuration consisting of one rotary variable volume control and fixed resistors is adopted. The regulation with the high accuracy and the reduction of the cost are thereby permitted. |
其他摘要 | 目的:通过降低门电路的电源电压,直到放大器的输出跟随所述电压,形成具有高精度的廉价激光驱动电路。组成:用于调节光电探测器输出的电路507被制成这样的配置,包括2kOMEGA可变电阻器VR2和R16:1kOMEGA,R17:2kOMEGA和R30:100OMEGA的固定电阻器。在电阻器R16,R17中存在跳线图案,并且提供切割点CP1-CP3。在110-3,100OMEGA之前,没有任何东西可以达到100-2,100OMEGA系列电阻RPD和CP1。该电路的构成是在2,100-4,100OMEGA之前切断CP2并在3,100-5,100OMEGA之前切断CP3。提高了调节精度,采用了由一个旋转可变音量控制和固定电阻组成的廉价配置。由此允许具有高精度和降低成本的调节。 |
