Distance measuring laser apparatus for delayed time measurements |
摘要 |
The present distance measuring laser apparatus measures the delayed time occurring between two signals derived from a laser beam and a reflected light beam and received in two separate channels. One channel is the reference channel and provides a starting signal when a light signal is emitted by the laser. The other channel is the measuring channel and provides a stop signal at the time of the return of a reflected light beam. An identical input circuit is provided in each signal channel. The receiver input rectifier or diode of each input circuit has a working impedance including a parallel resonance circuit made up of the barrier layer capacity of the diode, of an inductance coil and a further, external capacity.
