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 electronic s 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.
