An emitter and a receiver in a light barrier system are aligned by placing one or more retroreflective elements in a vicinity of the receiver such that a beam of visible light emitted by an optical alignment element impinges on a retroreflective element when the light beam emitted by the emitter impinges on the receiver. The optical alignment element is activated to emit a beam of visible light, and optical components of the system are adjusted so that the visible beam emitted by the optical alignment element impinges on, and is reflected by, the retroreflective element.

Method and system for aligning emitters and receivers of a light barrier by means of visible light

A first imager has a relatively high resolution and a relatively narrow first field-of-view. Information about objects in an environment is detected or captured, and used to steer the first field-of-view of the first imager. The sensor(s) may take the form of a second imager with a relatively lower resolution and relatively wider second field-of-view. Alternatively, other types of sensors, for instance presence/absence sensors may be employed. The first field-of-view may be directed toward an object that satisfies one or more conditions, for instance matching a particular SKU. The first field-of-view may track a moving object, for instance via a tracking mirror and actuator. This approach may be employed in retail locations, for example in grocery or convenience stores, for instance to reduce various forms of theft or in industrial environments.
