Summary
A contactless tracking photopotentiometer has been used for the first time for amplifying voltages and currents with a gain of K≥1. The new photoamplifier circuit is more universal as compared with the existing circuits, and possesses the following advantages.
-
1.
A highly linear amplifier amplitude characteristic.
-
2.
A higher current, and especially voltage gain.
-
3.
A virtual freedom of its gain from the inevitable variations in the voltage and current of the illuminator supply source.
-
4.
The possibility of obtaining with relative simplicity various functional transfer characteristics.
-
5.
A threshold of the amplifier's sensitivity determined by that of the mirror galvanometer.
