Infrared thermal imaging cameras or infrared cameras are essentially infrared radiation thermometers that measure the temperature at many points over a relatively large area to generate a two-dimensional image, called a thermogram, with each pixel representing a …

Infrared thermometers measure temperature by sensing the infrared energy which every material or object with a temperature above absolute zero (0 °K) will radiate. In the simplest configuration, a lens will focus the infrared radiation onto a detector which in turn will convert this energy into an electronic signal.

Infrared (IR) thermometers are useful in measuring temperature across a range of industrial and clinical environments. These non-contact temperature measurement devices function well in circumstances where the object is fragile and dangerous to get near to, or when other kinds of thermometers are not practical.

Infrared thermography (IRT) is a science dedicated to the acquisition and processing of thermal information from non-contact measurement devices [1]. It is based on infrared radiation (below red), a form of electromagnetic radiation with longer wavelengths than those of visible light.

A basic infrared thermometer (IRT) design, comprises a lens to collect the energy emitted by the target; a detector to convert the energy to an electrical signal; an emissivity adjustment to match the IRT calibration to the emitting characteristics of the object being measured; and an ambient temperature compensation circuit to ensure that ...

Each body with a temperature above the absolute zero (-273.15°C = 0 Kelvin) emits an electromagnetic radiation from its surface, which is proportional to its intrinsic tem-perature. A part of this so-called intrinsic radiation is inf-rared radiation, which can be used to measure a body’s temperature. This radiation penetrates the atmosphere.

An infrared thermometer measures temperature by detecting the infrared energy emitted by all materials which are at temperatures above absolute zero, (0°Kelvin). The most basic design consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of

Temperature measurement can be divided into two categories: contact and noncontact. Contact thermocouples, RTDs, and thermometers are the most prevalent in temperature measurement applications. They must contact the target as they measure their own temperature and they are relatively slow responding, but they are inexpensive.

Each body with a temperature above the absolute zero (–273,15 °C = 0 Kelvin) emits an electromagnetic radiation from its surface, which is proportional to its intrinsic tempera-ture. A part of this so-called intrinsic radiation is infrared radiation, which can be used to measure a body’s tempera-ture. This radiation penetrates the atmosphere.
