1. A special lens is used to focus the infrared rays emitted by objects in the field of view.

2. The phased array on the infrared detector element can scan the converged light. The detector element is capable of producing a very detailed temperature pattern called a thermogram. In about 1/30 of a second, the detector array can acquire temperature information and make a thermogram. This information is acquired from thousands of detection points in the field of view of the detector array.

3. The thermograms generated by the detector elements are converted into electrical pulses.

4. These pulses are sent to the signal processing unit - a circuit board with integrated precision chips that convert the information from the detector cells into data that the display can recognize.

5. The signal processing unit sends the information to the display, so that various colors are displayed on the display, and the color intensity is determined by the emission intensity of infrared rays. Combining the pulses from the detector cells creates an image.
