Abstract

An optical position locating device (10) comprises a frame (12) defining a generally rectilinear target zone (14), a pair of light sources, detectors and structure (24, 26) for directing the light initially from each light source to the target zone (14) and for scanning across the target zone and directing light returned from the target zone (14) to the associated detector. The target zone (14) is substantially rectangular and the two light sources and light detectors with their associated light directing structures (24, 26) are respectively positioned at each of a first and second corner of the target zone (14) along a common first side. A plurality of reflective structures (18, 20, 22) are arranged about the target zone (14) and include first (18) and second (20) reflector assemblies in generally mutually facing relationship to define second and third opposite sides of the target zone (14) and a third reflector assembly (22) defining the fourth side of the target zone (14) which is opposite the first side. Each of the first (18), second (20) and third (22) reflector assemblies comprising retroreflective material. <IMAGE>
