Abstract
The present invention generally relates to devices, systems, and methods for detecting and measuring the radiant power and emissivity of nonthermal far infrared radiation (FIR) in 3-16 μm wavelength spectrum from the surface of a FIR-photons emitting object and, more specifically, in 8-14 μm wavelength range.

A method for measuring nonthermal far infrared radiation emitting from the surface of a test object comprising:
- a) providing the test object;
- b) providing a temperature measuring means to measure the contact temperature of the test object;
- c) providing a blackbody reference source preset to a specified temperature;
- d) providing an infrared imaging device to capture thermal image of test object and blackbody reference;
- e) providing a processing apparatus to perform operations including acquiring, storing, analyzing, computing, and displaying the data of thermal image;
- f) providing a mathematical algorithm to execute blackbody related calculations;
- wherein steps a) through f) produce an approximated blackbody temperature for the test object;
- whereby a radiant power and an emissivity of test object's nonthermal far infrared radiation can be determined by comparing said approximated blackbody temperature to test object's contact temperature.
A system for measuring nonthermal far infrared radiation emitting from the surface of an test object comprising at least:
- a) a contact temperature measuring means,
- b) a blackbody reference source,
- c) an infrared imaging device, and
- d) a processing apparatus configured to execute a set of instructions for performing operations including acquiring test object's contact temperature, capturing a thermal image of test object and blackbody reference source, and computing grey values for the test object and blackbody reference source to produce an approximated blackbody temperature for the test object;
- whereby a radiant power and an emissivity of test object's nonthermal far infrared radiation can be determined by comparing said approximated blackbody temperature to test object's contact temperature.
A device for measuring nonthermal far infrared radiation emitting from the surface of an object comprising at least:
- a) an infrared camera for capturing thermal image of test object and a blackbody reference source;
- and
- b) a processing apparatus for executing instructions for performing operations including computing grey values of said thermal image to produce an approximated blackbody temperature for the test object, whereby a radiant power and an emissivity of test object's nonthermal far infrared radiation can be determined by comparing said approximated blackbody temperature to test object's contact temperature.
