ABSTRACT:
A distance measuring equipment which is useful in, for example, a collision prevention system wherein a laser beam is forward emitted from a vehicle to measure a distance between the vehicle and a forward vehicle, and an alarm is produced when the present vehicle abnormally approaches the forward vehicle. In the distance measuring equipment, when a correction instruction signal is supplied, a distance calculating circuit first drives an optically shielded light emitting element for correction to emit light, and produces a correction signal on the basis of a signal input into an adder connected to a light receiving element. Thereafter, the distance calculating circuit drives a light emitting element for measurement to emit light, and produces a distance measurement signal with referring the correction signal.
