Thermal detectors CHAPTER 07 1 Thermopile detectors

hollow space. Our thermopile detectors use materials that have a large Seebeck coefficient (thermal electromotive force) and are easily formed by the semiconductor process. When infrared light enters a thermopile detector having the above mentioned structure, the hot junction on the membrane heats up and produces a temperature

Thermopile - Wikipedia

A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Such a device works on the principle of the thermoelectric effect, , generating a voltage when its dissimilar metals (thermocouples) are exposed to a temperature difference.

Thermopile Voltage Low: What it Means and How to Fix It?

Having a basic understanding of how your unit works can be extremely helpful. Let’s dig in deep to explain what it means to encounter low thermopile voltage. When it comes to your hot water heater, the pilot light heats up the thermopile. As this occurs, they produce a small voltage of electricity that passes over to the gas control valve. A pilot light can go out. When this happens, there ...

Introduction to infrared vision | Resources | Opto Engineering

NETD is a widely used performance parameter that characterizes the sensitivity of thermal imaging sensors. NETD is the amount of incident signal temperature that would be needed to match the internal noise of the detector (such that the signal-to-noise ratio is equal to one). Essentially, it specifies the minimum detectable temperature difference. Typically NETD is expressed in units of Kelvin (K). …
