一、一般电子仪器,都备有稳压电源,以保证电压的稳定,否则其功效随电压下降有所影响。在野外作业的光电测距仪,只能应用直流电压,由于直流电压不稳定,不断下降,直观上感到影响精度,而片面追求高电压,否则不敢大胆地工作,这就浪费电源,也影响工作的积极性。为此,需要在理论上进行探讨,明确 First, the general electronic equipment, are equipped with a regulated power supply to ensure the stability of the voltage, or its effect with the voltage drop affected. Optoelectronic range finder operating in the field, only the application of DC voltage, due to DC voltage instability, falling, visually feel the impact of accuracy, and one-sided pursuit of high voltage, or dare not to work boldly, which is a waste of power, but also affect Enthusiasm for work To this end, we need to study in theory, clear
