Claim Text:
1. A method for determining emissivity of an object, comprising: irradiating a surface of the object with an infrared light beam; receiving reflected infrared light beams, reflected at the object, using an infrared camera having a detector with an acquisition area comprising a two-dimensional array of pixels; acquiring a first intensity of the reflected infrared light beams at each individual pixel in the acquisition area of the detector of the infrared camera; receiving reflected surrounding radiation reflected at the object and inherent radiation of the object using the infrared camera; acquiring a second intensity of the reflected surrounding radiation and the inherent radiation of the object at each individual pixel in the acquisition area of the detector of the infrared camera; for each individual pixel of the two-dimensional array of pixels in the acquisition area of the detector, adjusting the first intensity acquired at the respective pixel as a function of the second intensity acquired at the respective pixel, calculating the emissivity of the object based on the adjusted second intensity at each pixel of the two-dimensional array of pixels.
