PURPOSE:To improve the accuracy in detection by generating time-serially the 1st and 2nd electrical signals conforming to the distance to an object to be measured, amplifying and storing the signals and outputting a signal indicating the distance by calculation. CONSTITUTION:The 1st output from a means 1 for generating information on distance measurement is fed by a control means 2 to a signal processing circuit 3. The output from the circuit 3 is fed by a switch means 4 controlled by the means 2 to a storage means and is held therein. The means 1 controlled by the means 2 feeds the 2nd output to the circuit 3. The output from the circuit 3 is fed to an arithmetic means 6 by the means 4 changed over by the means 2 without passing the same through a storage means 5 and at the same time the signal from the means 5 is fed by the means 2 to the means 6, by which the results of the arithmetic operation is calculated. The result of the arithmetic operation is calculated. The result of the arithmetic operation is judged by a distance judging means 7 and is fed as distance information to the succeeding stage. |
