and amplitude as illustrated in fig2 a and 2b to produce fig3 to 6 the processing steps described below were simulated simulation was performed to make the representation more understandable simulation also takes into account the problems of extracting very fast low energy signals without interference from the complex circuit in fig2 through 6 the abscissa specifies the object distance in meters distance is proportional to the time delay in accordance with distance 1 2 u00d7 velocity of light u00d7 delay fig1 illustrates a light pulse transmitter 1 a light reflecting object 2 and a light receiver 3 which form an optical pulse delay measuring system the light pulse transmitter 1 includes for example a gaas laser diode with a power supply pulse shaping circuitry for pulse shaping in the nanosecond range and stabilization circuitry the object 2 is shown as a triple reflector that is as a cooperative element however the invention is particularly advantageously used with arbitrary diffusely reflecting objects such as machine parts buildings and the like an avalanche photodiode with a power supply and circuitry to regulate the operating range is used as light receiver 3 typically light pulse transmitter 1 and light receiver 3 also contain optics for generating and receiving a suitably shaped transmitted and received light beam continuous wave light components are.
