The temperature spectrum generated by the night vision detector element is converted into electrical pulses. These pulses are transmitted to a signal processing unit, a circuit board integrated with a precision chip, which converts the information emitted by the detector element into data that the display can recognize. The signal processing unit transmits information to the display, thereby presenting various colors on the display. The color intensity is determined by the emission intensity of infrared rays. The pulses transmitted from the detector element are combined to generate an image.
