Abstract: A distance measurement device includes: a pulse light emitter that emits pulse light to a measurement target; an optical sensor that receives reflected light which is the pulse light reflected by the measurement target; and a controller that controls a light emission timing of the pulse light emitted by the pulse light emitter, and determines a distance to the measurement target, from a light reception timing of the reflected light detected by the optical sensor. The controller sets the light emission timing in each of N periods (N being a natural number less than K) selected randomly from continuous K periods (K being a natural number greater than or equal to 2) to a timing that is delayed by a random first time from a start time of the period.

Abstract: A distance measuring device is to be connected to a wave transmitter and a wave receiver. The distance measuring device includes a distance measuring unit, which calculates a distance to the target based on a time interval between transmission of a measuring wave from a wave transmitter and reception of the measuring wave at a wave receiver. The target may be present across a preceding distance range and a succeeding distance range which are continuous with each other and both of which belong to a plurality of distance ranges defined by dividing a measurable distance range. In such a situation, the distance measuring unit calculates the distance to the target based on respective amounts of a preceding wave received at the wave receiver over a period corresponding to the preceding distance range and a succeeding wave received at the wave receiver over a period corresponding to the succeeding distance range.

Abstract: A distance measuring device includes a controller and a distance calculator. The controller sets, in a first time period, a first measurement time range corresponding to a first measurement distance range; causes a light emitter to emit light and places a light receiver into an exposure state, in the first measurement time range; sets, in a second time period, a second measurement time range corresponding to a second measurement distance range; and causes the light emitter to emit light and places the light receiver into an exposure state, in the second measurement time range. At least one measurement condition is different between the first and second time periods. The distance calculator calculates the distance from the distance measuring device to a measurement target, based on the time from the emission to the reflection of light. The time is in at least one of the first and second time periods.
