ABSTRACT:
Disclosed is a distance measuring equipment comprising: a light emitting element for generating a pulse beam; and a light receiving element for receiving a reflected pulse beam from an object under measurement with respect to the pulse beam generated from the light emitting element and converting the reflected pulse beam into an electric light receiving signal. The distance measuring equipment also comprises: an object detecting element for detecting the under-measurement object on the basis of a level of an output signal of the light receiving signal through the light receiving element; and a calculating element for calculating, when the object detecting element detects the under-measurement object, a distance to the under-measurement object on the basis of a time obtained by subtracting a predetermined time corresponding to a half-value of a pulse width of the light receiving signal from a delay time from a generation of the pulse beam through the light emitting element to a reach of a peak of the light receiving signal through the light receiving element.
