Introduction to Electro-optics sensor

Electro-optica sensors are basicaly electonic detectors that sbcailly converts the light eneregy oor change a light into electricacl eneregy.

These sensors are capable of detecting electromagnetic radiation from infrared to ultraviolet wavelengths. One can visit website of pfg optics to know about the flat optics and custom spherical optics manufacturer. They are used in a wide range of applications such as consumer and industrial application, for example:

  1. Position sensors that activates the object interrupts a light beam.
  2. Photoelectric sensros that deetcts the absence, distance or presence of an object.
  3. Lamp that gets turn on automatically in response to darkness.
  4. Flash deetction, in order to synchronize one photographic flash to another.


An optical sensor converts light rays into electronic signals. It measures a physical quantity of light and then translates it into a form that can be read by an instrument. An optcal sensors is basiccally part of a larger sytem that consist of a soruce of light, the optical sensor and a measuring device. It is often connected to an electrical trigger. The trigger light reacts to a change in signal within the sensor. An optical sensor can measure changes in one or more beams of light. When the cahnge takes place, a photoeletric trigger is operated by a light sensor and in result it either increases or decreases the eletrical output.

An optical switch basically allows the signals in optical fiber or integrated optical circuits to be changes from one sircuit to another. An optical switch may operate by mechanical means or by electro-optic effects, magneto-optic effects as well as other means. Optical switches are optoelectronic devices that can be integrated with integrated or discrete microelectronic circuits.


In all the cases where there is need to convert light energy into eletrical eenregy. Because of this fact, electro-optical has a wide range of applications. Common applications are smartphones where the sensor is used to adjust screen brightness, and smartwatches in which the sensor is used to measure the wearer’s heartbeat. Optical sensors are also used in the eneregy field to monitor structures that produce, convert, generate, and distribute eletrical power. The distributed and non-conductive nature of optical fiber makes optical sensors perfect for oil and gas applications, including pipeline monitoring. Optical sensors are also used in offshore platform monitoring, wind turbine blade monitoring, downhole monitoring, and power line monitoring
