The Basics of Optical Sensors and Common Types
2023年3月23日 · Optical sensors are one of the most popular sensor types in industrial automation. This article covers optical sensor basics and commonly used types, including fiber optic, photoelectric, and optical encoders.
Optical Transmissive Sensors The basic elements of an optical transmissive sensor also known as Photo interrupter are an emitter and a photo detector. Typically an IRED (Infrared emitting diode) and a Phototransistor is used. Figure 2 shows a typical circuit. The anode of the IRED is connected to the power supply via the resistor RIF and the ...
A reflex sensor is used in order to receive a reflected signal from an object. This signal gives information on the position, movement, size or condition (e.g. coding) of the object in question. The parameter that describes the function of the optical coupling precisely is the so-called optical transfer function (OT) of the sensor.
Understanding Optical Sensors: Types, Principles, and Applications
2024年5月24日 · Optical sensors detect the location or presence of objects by emitting light and capturing reflections or interruptions of these rays. The sensor uses light-emitting diodes (LEDs) to emit a beam of light. When this beam encounters an object, it can be reflected to the sensor or blocked by the object. Figure 3: Working Principle of Optical Sensor.
