摘要： A non-contact thermal imaging system based on infrared radiation detection is described which uses an energy source to provide a beam of energy that strikes a sample to be analyzed. The energy beam produces a thermal wave in the sample, there being infrared radiation emitted from the thermal wave. All of the infrared radiation emitted from the heated area of the sample is collected and directed to an infrared detector, to have a two-dimensional image of the sample. This is used to detect surface and sub-surface structure, defects, etc. The use of a focussed energy beam, such as a laser or electron beam, offers advantages. In this technique, all points of the sample are treated equally and the results are very easily interpreted to know the exact location and type of structure that is imaged in the heated area. An ellipsoidal collector is preferrably used to image the emitted infrared radiation onto the detector, where the sample is located at one focal point of the ellipse, and the detector is located at the other focal point.

摘要： In an analyzing apparatus for analyzing compositions using a fluorescent X-ray in the atmosphere, a calibration to eliminate influences caused by a time-dependent change is performed. The analyzing apparatus includes an emission unit, a detection unit, an environment measurement unit, and a time-dependent change calculation unit. The emission unit emits a primary X-ray. The detection unit detects an intensity of a secondary X-ray passing through the atmosphere. The environment measurement unit measures an environment parameter defining the atmosphere. The time-dependent change calculation unit calculates a time-dependent change of the intensity of the secondary X-ray between a first timing and a second timing, based on a first environment parameter, a first intensity of the secondary X-ray, a second environment parameter, and a second intensity of the secondary X-ray.
