Abstract

A system and method for an optical displacement detector system with adjustable pattern direction are disclosed. In an embodiment, the detector system 20 includes a mounting bracket 110 and a sensor assembly 50. The sensor assembly 50 includes a housing 120, and a sensor module 100 in the housing 120. The sensor assembly 50 can be rotated with respect to the mounting bracket 110 to adjust an optical axis 112 of the sensor module 100. In another embodiment, the detector system includes a turntable that enables additional adjustment of the optical axis 112. Such a system significantly improves installation of these detector systems as compared to existing optical displacement detector systems, which have fixed optical axes. In one application, the detector system is installed in a door system having a door and door frame, and detects displacement of the door. The sensor module 100 includes a time to flight analyzing sensor 152, a trigger sensor 142, a battery 101, and system state light emitting diode (LED) 111. The time to flight analyzing sensor 152 and the trigger sensor 142 are mounted to a printed circuit board 150 and emit beams of light along their respective optical axes 112-152 and 112-142. The optical axes 112-142 and 112-152 are close in distance to one another and are substantially parallel to one another. The analyzing sensor 152 can have a high power consumption, and the trigger sensor 142 is low in power/current consumption. The detector system 20 also includes a sensor assembly fixing system to fix the rotation of the sensor assembly 50 after completing calibration/adjustment of the optical axis 112. The sensor assembly fixing system prevents rotation of the sensor assembly 50 in the mounting bracket 110. In examples, the sensor assembly fixing system is a set screw 14.
