About infrared thermometers and thermal imaging applications
Infrared thermometer and thermal imaging According to the different detection functions, infrared radiometer has infrared thermometer and infrared thermal imaging two types.
1. Infrared thermometer
Infrared thermometer, also known as the point temperature meter. This is a new type of thermometer developed faster in recent years, used to measure the temperature of a fixed point of the object. With small size, light weight, high sensitivity, fast response, simple operation and other advantages, very suitable for on-site equipment temperature detection. Infrared radiation through the transmission or reflection optical system, made by the modulator of alternating radiation, through the infrared detector, by the electronic amplifier processing and improve the signal-to-noise ratio, and finally by the indicator to give the temperature of the object being measured.

2.Thermal Imager
This is the use of object thermal radiation characteristics, the plane and space temperature distribution of the object under test to graphic representation of the temperature measurement equipment, which is based on infrared detectors, optical scanning method of sequential scanning throughout the scene space, after conversion, the visible image on the display, can show the shape of the object and the distribution of the temperature field. Use it to analyse the state of the equipment in operation, to identify its faults, is very effective. However, it is currently expensive and its popularity is limited.
Infrared radiation through the scanning lens made of infrared optical material, after focusing, and then through a vertical scanning prism and a horizontal scanning prism, after continuous scanning, instantaneous airport scanning the entire subject. The infrared beam output from the horizontal prism passes through a set of relay optics including selectable apertures and filters, and is finally focused on an infrared detector. The detector unit produces an electrical signal output proportional to the radiation from the target, which is amplified to produce a video signal that is sent via connecting cables to a cathode ray tube display, which shows a black and white or colour image with adjustable brightness or a quantitative thermal image.
