This study can be a helping hand in future for the people who want to acquire any particular detail or information on any one of these sensors. This research work adds another information about tested sensor for anyone trying to get hands on information for the three sensors or their applications. Keywords: sensor; calibration; gauge, measurement. 1. Introduction Optical distance sensors are the result of decades of opto-electronics research & innovation. This branch of photonics deals with the use of electronic devices that track, produce and modulate light in order to perform an incredibly diverse range of functions. Light can be used to measure the distance of a sensor to a barrier or substrate in the scope of distance measurement. Optoelectronic instruments are associated with the permeability of sub-visible ionizing radiation (gamma, X-rays, etc.), although in the visible and TI - Optical Distance Sensors JF - Acta Mechanica Slovaca DO - 10.21496/ams.2021.034 DA - 2021-09-29 UR - https://www.deepdyve.com/lp/unpaywall/optical-distance-sensors-fPRMNw0qlE DP - DeepDyve ER -
