Abstract
Specific devices and systems associated with aligning sensors to targets are disclosed herein. More specifically, systems that utilize light guides for aligning scanning surfaces of scanning devices with target surfaces of scan targets are disclosed herein. One disclosed device comprises a body, a sensor fixed to the body, and at least two apertures aligned with the sensor. The apertures define visible light patterns. The visible light of the visible light patterns can be generated by at least one light source that emits light through the at least two apertures. The visible light patterns exhibit a unique combined representation when projected at a target that is at the optimal front focal distance from the sensor. The visible light patterns also independently exhibit first and second universal representations when projected at a target surface that is at the optimal orientation relative to the sensor.
