EXPERIMENT 3: INFRARED MEASUREMENTS 
 
1. Purpose 
• To increase an understanding of the fundamentals of IR detection (heat detection); 
• To investigate its measurement techniques and their limiting factors; 
• To further familiarise yourselves with the measurement facilities. 
 
2. Equipment list 
• Targets of varying objects (low temperature aluminium plate, resistor)  
• Thermovision A320 IR system 
• Raytek Infrared Thermometer  
• TES Thermometer 
 
3. Introduction 
IR measurements are performed to determine the temperature of different objects/targets and  
also to distinguish each object within an environment. IR systems are used for military 
applications such as IR-guided missiles or night vision devices. For commercial applications, it 
is utilized in electronic circuit board trouble shooting, home automated system, and robotic 
toys.

5. Procedures 
 
In this laboratory, you will measure the temperature of two objects (a flat aluminium sheet, and a 
resistor). When measuring the temperature using IR system you may assume t and A , and

R =1. 
5.1 FLIR A320 Thermal Camera has been tested and found to be displaying 2 ºC above the actual 
temperature of the objects found from the Raytec ST Thermometer (may change slightly). In 
the object parameters change the Transmission coefficient and Humidity to 1.0 and 50% 
respectively and input Atmospheric and reflected Temperatures. Place the resistor at a small 
distance (approx. 0.5m) and measure the temperature of the resistor and hence determine the 
emissivity of the resistor.

Report 
Infrared Radar Systems 
Introduction: Infrared radar systems are widely used in defense. These systems detect objects by 
detecting the infrared radiations emitted by the target objects. Due to passive nature [does not send 
signals from the radar, just detects whatever radiations are coming in], IR radars are difficult to detect, if 
employed somewhere.  
I have tried my best to visualize the set up and experiment procedure as the details are missing in the 
experiment brochure.  
In this experiment we are trying to calculate temperature of 2 objects – an Aluminum Plate and a 
resistor. Using Plank’s radiation law and Wein’s Formula, we will plot the radiation spectrum curves for 
both the objects and find out maximum radiation wavelengths and check whether the objects are 
radiating at maximum wavelengths.  
We are observing limited amount of radiation spectrum in the image [of FLIR software] as the Camera 
has a spectral range [7.5 μm – 13 μm], using the Plank’s Law, we will calculate the Total Radiation 
Intensity in this range of wavelength. 
First let’s list the results from Part 5 of the lab: [I have made some assumptions in this part, I’ll mention 
as we go along.] 
 Placed Near (0.6m) Placed Far(8.8m) 
Resistor                                   
 
 Placed Near (0.6m) Placed Far (8.8m) 
Al Plate
Resistor at High Temp.                   
 
The adjusted transmission coefficient for resistor is equal to 0.90 and for Aluminum Plate, it is 0.94. 
Since, you had covered both the objects with black material, these object can be considered as Grey 
Objects, thus ε = 0.9 can be assumed. 
 
With this amount of information, we will answer questions asked in part 6  

Comment [kb1]: In the lab experiment pdf, 
it was recommended to put resistor/plate at 
8.8m distance, so I have written 8.8m. 
However, when I see the image ‘2 far res.JPG’, 
in the object parameters, you have used 0.6m. 
Please check it.  
Comment [kb2]: Here also, In the Al 
close.JPG, I see 0.7m distance and 
In Al far. JPG distance has been put 0.6m. 
Please check this.
