    Abstract: In an optical distance measuring apparatus, a light source irradiates a target object with a light pulse having a first pulse width. A light receiver outputs a pulse signal that represents reflection light from the target object being incident on the light receiver, and has a second pulse width that is larger than or equal to the first pulse width. A histogram generator records, every predetermined period, a frequency representing the number of outputted pulse signals to thereby generate a histogram. A peak detector detects, from the histogram, an edge point of a peak figure included in the histogram. A distance calculator subtracts, from a time indicative of the edge point of the peak figure, a time length of the second pulse width to thereby calculate a target time, and calculates a distance to the target object as a function of the calculated target time.

  • Patent number: 11536811
    Abstract: A distance measuring device includes a pulsed laser source, a light receiving unit and a computing module. The pulsed laser source emits a laser pulse to a target in accordance with a predetermined period. The light receiving unit has a photon receiving type of light receiving element that receives incident light and outputs a binary pulse, and the binary pulse is used to indicate whether a photon receiving event occurs. The computing module is configured to receive the binary pulse and determine whether an inter-period coincidence event occurs, and the inter-period coincidence event is defined by detecting a plurality of photon receiving events exceeding a predetermined count, on relative positions in a predetermined period number of the predetermined periods. If the calculation module determines that the inter-period coincidence event occurs, a distance of the target is calculated according to time information related to the inter-period coincidence event.
