Description
The EOP-AGC-PC driver, a close loop feedback amplifier, operates a broad range of resonant optical scanners and resonant optical choppers at their natural frequency. The driver has an Automatic Gain Control circuit which automatically regulates the motion amplitude of the resonant device. It improves amplitude stability by approximately 10 times compared tot he unregulated drivers and provides precise control for a wide temperature range.
Both sine wave and TTL level square wave are provided as reference signals. A trimpot control permits the user to adjust the phase of the reference signals with respect to the position of the mirror or the vane. The adjustable range is 180°. A second trimpot provides amplitude adjustment in the range of 10% to 100% of the full amplitude.
