Measurement in a longer distance range can be made with this system. ABSTRACT OF THE DISCLOSURE The optical displacement sensor modulates intensity of the light beam as a function of the physical displacement. They are made of an incremental optical encoder activated by the stroke of a winding or unwinding stainless steel wire 01.

The receiver element detects reflected light from the object. Most interferometry-based sensors require a highly coherent laser and a highly stable optical setup they are. The lead-in fiber tip consists of a millimeter-long segment of coupled-core optical fiber fusion spliced to a conventional single mode fiber.

The sensor is based on an optically resonant cavity whose cavity length is affected by the environmental stimulus. An optical displacement sensor takes in a plurality of images of a target object by projecting a slit beam of light and using a two-dimensional image taking element by changing the image taking. The external element target of the sensor is a microscope slide which.

A triangulation sensor 200 according to the second embodiment is made up of a head body 202 serving as a first housing and a relay part 204 serving as a second housing and a relay cable. The optical displacement sensor exhibits an optical design that has suppressed back reflection and improved alignment tolerance between its optical components. This invention relates to an optical displacement sensor element eg.

Optical fiber displacement sensors have attracted a lot of research interests in recent years Compared with electrical sensors optical fiber displacement sensor has many advantages such as high sensitivity large dynamic range long sensing distance high electromagnetic interference resistance and so on. AU - Beth M. Optical sensors using reflected scattered or light to infer displacement of force There are a number of related works which use closely-related transduction approaches injecting light into a sensing component and inferring force or deformation of the tactile sensor surface by analysing the light collected at a detector.
