How UV, IR and Imaging Detectors Work

An IR detector is a pyroelectric sensor that is capable of detecting thermal radiation and is rather sensitive to variations of the received light signal. A tantalum/lithium crystal is associated with an OP amp or a field-effect transistor. An optical filter (a spectral gate) chooses a specific spectral band or wavelength ( µm, µm, 4 to 5 µm…). The crystal perceives the random ...

Infrared Temperature Sensor: what is it and how does it work?

2009-09-14· An infrared temperature sensor used in contact-type instruments include thermocouples, resistance temperature detectors (RTDs), thermistors, and semiconductor temperature sensors. Since contact sensors measure their own temperature they require physical contact with the measured object to bring the sensor body to the object’s temperature.

How Does an Infrared Detector Work? | Cove Security

The cameras are installed with IR detection and begin to record the moment the thermal security camera detects movement within the frame. This stops the camera from recording pointless hours of blank footage. Now, the wireless infrared camera only catches the important moments. This saves money, time, and energy to ensure that the homeowners are getting the most out of their home …

Key Parameters of Infrared Thermal Imaging Detectors

Key Parameters of Infrared Thermal Imaging Detectors. Array format (resolution): the number of effective pixels when the infrared detector detects the target and output a thermal image/video. The higher the resolution is, the smaller the target can be detected and the longer the detection distance is, the higher the recognition possibility of the target will be.

Infrared detector - Wikipedia

An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Bolometers and microbolometers are based on changes in resistance. Thermocouples and thermopiles use the thermoelectric effect. Golay ...

Infrared Temperature Sensor: what is it and how does it work?

2009-09-14· Thermal IR detectors absorb the incident energy, raise the sensing element temperature, and change the detector’s electrical properties: thermopiles generate thermoelectric voltage, bolometers change resistance, and pyroelectric devices change their polarization. In general, they are slower than photo detectors. A thermopile is made by connecting several thermocouples in series and placing ...
