Optical position sensors, are one of the main equipment in laser ray tracing systems. Since these sensors are used in different applications, the weaknesses and strengths of choice for the intended use is of utmost importance. In this paper, the structure of optical detectors are checked. Then, the detector along the respective parameters, are analyzed. The strengths and weaknesses of each study are determined and the results are compared in the table

sensitive position detector, foursome detector, photodiodes, photodiode side effects, laser ray tracing
