How infrared thermometer/ thermal scanner works?
Now a days CORONA virus is increasing so it emits lots of radiation and it increases temperature and for checking every where lots of thermal scanner is used.
so lets check the How its work
For understanding Infrared thermometer first need to understand about the LASER its full form is as under

L = Light
A = Amplification of
S = Simulated
E = Emission of
R = Radiation
As comparing to normal torch it provides continuous same color and concentrate on one point its not fade over the path there are some reason for having laser properties below:
- it is wavelength is monochromatic:depends on the color of the light produced by that monochromatic source
- it is coherent :two wave sources are perfectly coherent if they have a constant phase difference and the same frequency
How infrared thermometer/ thermal scanner works?
infrared thermometer/ thermal scanner : it uses the LASER to check the temperature in Celsius
this scanner not check the inner temperature of body it just check the skin temperature
How infrared thermometer/ thermal scanner works?
any material in world which heated it emits the radiation
it is the radiation which emits from sun
there are three types of the light emits from sun is
- Ultraviolet light
- Invisible light
- Infrared light
any body temperature = infrared wave length
there is diagram shows below:
as shown in figure Thermometer works ray apply to body / material which emits energy than replied ray is different from ray applied than difference is measured and display on the screen
it specification and what it indicates:
distance to spot ration - 12:1 (Distance in ft :diameter of spot in ft)
it very important to check the distance to spot ratio if distance is more than you will not get the perfect temperature
The LASER in the thermal scanners is just to point out that you are measuring the the part
