A Tutorial on Electro-Optical/Infrared (EO/IR) Theory and ...

EO/IR sensor is integrated. Performance of an EO/IR sensor depends upon the optics, detector, and display, in addition to factors mentioned it is unwise to evaluate the potential utility of an EO/IR sensor from specifications alone, that is, without using a detailed engineering model. Nevertheless, all other things being equal, it can be argued that, for an imaging sensor designed ...

Basics of IR Sensor | IR LED Pin Diagram & Working

· IR sensors find a wide variety of applications in various fields. Let’s take a look at few of them. Proximity Sensors . Proximity sensors employ reflective indirect incidence principle. The photodiode receives the radiation emitted by the IR LED once reflected back by the object. Closer the object, higher will be the intensity of the incident radiation on the photodiode. This intensity is ...

TOP 250+ Infrared Sensor Interview Questions and Answers ...

· Question 6. What Are The Smallest Target Ir Sensors Can Measure? Answer : IR sensors measure targets as small as .43mm (.017 in). The limitation is the temperature and emissivity. As the temperature goes lower or the emissivity is lower, then the instrument cannot go as small in spot size. The sensor will have to be placed closer to the target ...
