thermopile is used for detecting

Thermopile laser sensor - Wikipedia

Thermopile laser sensors (Fig 1) are used for measuring laser power from a few µW to several W (see section ). The incoming radiation of the laser is converted into heat energy at the surface. This heat input produces a temperature gradient across the sensor. Making use of the thermoelectric effect a voltage is generated by this temperature gradient.

Temperature-based Detection by IR MEMS Thermopile Array ...

· This enables a thermopile to detect a broad spectrum ranging from the ultraviolet to the infrared bands. An optical band-pass filter ensures that only a certain spectrum is filtered through – the spectrum in use will vary from application to application. The thermopile elements arranged into a matrix form the array. They read the object and ambient temperature, which enables the direction of ...

An Introduction to Thermopile Detectors

A thermopile detector is a passive radiation sensing voltage-generating device. It does not emit any radiation and require cooling or bias. Dexter Research Center (DRC) provides stable, high output radiation sensing thermopile detectors covering linear dynamic range from the UV to long wave IR. The spectral absorption of DRC detectors is flat from the ultraviolet to the far infrared. Based on ...

Thermocouple vs. Thermopile: A Complete Comparison | Linquip

· Thermopile Definition. A thermopile is an electronic instrument that modifies thermal power into an electrical one. It is also introduced as a Power pile. A thermopile may include several thermocouples combined normally in series or rarely in parallel forms. This format of connection can produce more outputs than employing a single thermocouple.
