5kHz electric eye oscillation circuit

This circuit can generate 5kHz, 5V pulse only when electric eye is shined by its incidental LED. Repeat frequency changes along with illumination intensity. So the break off or weaken of optical line can generate frequency variation. This frequency variation is easy to detect. It can be usedfor controlling signal. This circuit can be applied to invalidation-safe interrupt monitor and illumination transducer. If the beam isinterrupted completely, or very strong optical line shines on electric eye, the circuit stops oscillation.
