Abstract: According to a method and apparatus taught herein, an optical sensor uses pattern recognition in its optical detection processing to see detection patterns that correspond to predefined configuration settings. In one embodiment, for example, an optical sensing system selects an operational configuration by detecting a pattern embodied in received light data and comparing the detected pattern to one or more internally stored patterns. Each stored pattern represents a different operational configuration of the optical sensing system. If the detected pattern matches one of the stored patterns, the optical sensing system adopts the operational configuration corresponding to the matched stored pattern. Further, in one or more embodiments, the optical sensing system enters a configuration mode by an external stimulus, e.g., responsive to a configuration mode input, and the aforementioned pattern detection-based configuration selection is enabled only while in the configuration mode.

Abstract: A laser scanner apparatus (10) emits a laser pulse (14) and monitors for pulse reflections, with the relative timing of a reflected pulse (18) detected by the apparatus (10) being translated into an object distance according to Time-of-Flight (ToF) measurements performed by the apparatus (10). According to an example configuration or an example method (900) of operation, the apparatus (10) adjusts its ToF determination for reflected pulses (18) that are characterized as merged pulses formed by two or more overlapping reflected pulses (18). Among other advantages, the adjusted ToF determination yields a more accurate distance determination with respect to the earliest-arriving one(s) among the overlapping reflected pulses (18).

Abstract: Various embodiments of a laser scanner apparatus (10) and a method (1400) of operating a laser scanner apparatus (10), as disclosed herein, include the use of a variably blocked aperture (46) or a controlled defocusing in relation to receiving backscattered light (18). One or more embodiments combine both variable blocking and defocusing and may use a lens design that complements the blocking and defocusing. Among the various advantages offered by one or more embodiments disclosed herein is a laser scanner apparatus (10) that exhibits a flatter response curve to backscattered light (18) over a defined range of distances. That is, among other advantages of the configurations and operating methods disclosed herein, a laser scanner apparatus (10) experiences less variation in the optical power delivered to its photodetector (54) arrangement, in relation to detecting an object at different distances within a defined range.
