IPC: G01S17/93
Filed: 1993-12-21
Abstract: PURPOSE:To suppress the dispersion of the measured distance while securing the safety for eyes of a human in particular by providing a transmitted light control means controlling the transmitted light power based on the received light power. CONSTITUTION:Pulse light is emitted from a light transmitter 1 by the clock pulses from a clock pulse generator 2. The reflected light from an object 7 is received by a light receiver 3, and the received signal is inputted into a sample hold circuit 5. A sample pulse generator 4 counts how many times clock pulses are generated. A CPU 6 obtains the distance to the object 7 based on it. The CPU 6 has the function as a transmitted light control means and adjusts the transmitted light power based on the received light power via the function. When the present received light power is high, the next transmitted light power is made low. When the present received light power is low, the next transmitted light power is made high. The transmitted light power is controlled by the CPU 6 according to the received light power at that time.

A DC 1500V voltage becomes an input voltage V1 in a DC stringing section whereas a 2000V voltage converted through an auxiliary rectifier 21 into DC voltage becomes an input voltage V1 in an AC stringing section. More specifically, converted voltage in AC stringing section is higher than that in DC stringing section. A control circuit 11 determines these stringing sections based on the magnitude of peak charging voltage of a DC filter capacitor 4. Decision criterion of quick start operation, i.e., the set the level of charging voltage V2 of the DC filter capacitor 4, is switched between AC and DC stringing sections.
