Figure oscillating signal generated by the base when the circuit 555 by emitting diode emitting element and a light guide phototransistor added 4538 plastic flip-resonant oscillator output once have tiny displacement of the reflected light intensity changes, multivibrator device will flip the output signal UA changes can be detected from the surface of the small displacement. Guiding light emitting element as shown in Figure small displacement detection circuit diagram:
