The figure a shows the circuit with the 200 amplification factor, the bandwidth is 0 to 100KHZ, and it can be used in the preamplification of the 1m laser length measuring machine stripe counter. The figure b shows the circuit with the 50 amplification factor, the bandwidth is 0~200KHZ, the phase difference of the two photocells output signal is 180°, and it is amplified by the 5G922. This circuit can be used in the preamplification of the grating moore stripe subdivision circuit.
