摘要： A sensor device includes a source of radiation and a reflective surface having a contour that directs radiation reflected from the surface along a field having at least two parallel sides. In a disclosed example, the reflective surface contour is at least partially curvilinear. A disclosed example includes a laser diode as the source of radiation and the reflective surface directs the reflected radiation in a direction that is generally perpendicular relative to a path that light follows as it emanates from the laser diode. The reflective surface in one example shapes the reflected radiation from a source that provides radiation along a path with obliquely oriented sides, the reflected radiation has at least two parallel sides. A disclosed sensor device is useful for measuring at least one feature of a part or object placed within a field of view of a sensing element that can detect the reflected radiation.
