C inm 10nm 100 10 100 1m Akm Wavelength Infrared Figure 8 5 Electromagnetic Spectrum The primary source of infrared radiation is heat or thermal radiation Any object which has a temperature radiates in the infrared portion of the electromagnetic spectrum Even objects that are very cold such as an ice cube emit infrared When an object is not quite hot enough to radiate visible light it will emit most of its energy in the infrared For example hot charcoal may not give off light but it does emit infrared radiation which we feel as heat The warmer the object the more infrared radiation it emits Infrared cameras produce an image of invisible infrared or heat radiation that is unseen by the human eye There are no colors or shades of gray in infrared only varying intensities of radiated energy The infrared imager converts this energy into an image that we can interpret Several detector technologies exist the sensor in the PathFindIR LE is of the latest solid state design offering long life and fully automatic image optimization contrast and gain True thermal imagers should not be confused with infrared illuminator cameras that are often presented as simply infrared cameras There are hundreds of low cost infrared illuminated cameras on the market at prices below 100 These cameras do not produce the same image because they d2. discovered the infrared Many patents were issued for devices to detect personnel artillery aircraft ships and even icebergs The first operating systems in the modern sense began to be developed during the 1914 18 war when both sides had research programs devoted to the military exploitation of the infrared These programs included experimental systems for enemy intrusion detection remote temperature sensing secure communications and flying torpedo guidance An infrared search system tested during this period was able to detect an approaching airplane at a distance of 1 5 km 0 94 miles or a person more than 300 meters 984 ft away The most sensitive systems up to this time were all based upon variations of the bolometer idea but the period between the two wars saw the development of two revolutionary new infrared detectors the image 26 May 08 334 0001 00 10 LE rev 100 8 Infrared Technology converter and the photon detector At first the image converter received the greatest attention by the military because it enabled an observer for the first time in history to literally see in the dark However the sensitivity of the image converter was limited to the near infrared wavelengths and the most interesting military targets i e enemy soldiers had to be illuminated by infrared search beams Since this involved the risk of giving away the observer s position to a similarly equipped enemy observer
3. it is understandable that military interest in the image converter eventually faded The tactical military disadvantages of so called active i e search beam equipped thermal imaging systems provided impetus following the 1939 45 war for extensive secret military infrared research programs into the possibilities of developing passive no search beam systems around the extremely sensitive photon detector During this period military secrecy regulations completely prevented disclosure of the status of infrared imaging technology This secrecy only began to be lifted in the middle of the 1950 s and from that time adequate thermal imaging devices finally began to be available to civilian science and industry 8 2 How do Infrared Cameras Work Infrared energy is part of a complete range of radiation called the electromagnetic spectrum The electromagnetic spectrum includes gamma rays X rays ultraviolet visible infrared microwaves RADAR and radio waves The only difference between these different types of radiation is their wavelength or frequency All of these forms of radiation travel at the speed of light 186 000 miles or 300 000 000 meters per second vacuum Infrared radiation lies between the visible and RADAR portions of the electromagnetic spectrum Thus infrared waves have wavelengths longer than visible and shorter than RADAR 334 0001 00 10 rev 100 May 8 27 8 Infrared Technology
