1.2.6. OPTICAL FUNCTION
The optical functions include an objective lens, thermal imaging
detector, display and eyepiece. Infrared energy is emitted propor-
tionally to the temperature of an object. The warmer the object, the
more energy it emits. The infrared energy from the objects is fo-
cused by the optics, onto an infrared detector. The information from
infrared detector is passed to electronics for image processing. The
signal processing circuitry translates the infrared detector data into
an image that can be viewed on the built-in oleD display. The im-
age is observed through an eyepiece by operator.
1.2.7. ELECTRICAL FUNCTION
The electronic circuit is powered by replaceable four 3v lithium bat-
teries (cr123a).
Thor can be connected to an external 12 vDc/ 2a power supply
using video cable.
power from the batteries or external power supply is supplied to the
components through the on/oFF switch button.
