Mechanical Functions; Optical Functions; Electrical Functions - ATN OTS-30 Operator's Manual

1.2.5. MECHANICAL FUNCTION
The mechanical adjustments of the OTS sights allow for physi-
cal differences between individual operators using the system.
The scope functions include the switchboard, recalibrate switch,
universal connector, eyepiece diopter adjustment ring, battery
compartment cover, mounting rail. The mechanical controls are
identified in Figure 1-4.

1.2.6. OPTICAL FUNCTION
The optical functions include an objective lens, thermal imaging de-
tector and eyepiece. Infrared energy is emitted proportionally to the
temperature of an object. The warmer the object, the more energy it
emits. The infrared energy from the objects is focused by the optics,
onto an infrared detector. The information from infrared detector
is passed to electronics for image processing. The signal proces-
sing circuitry translates the infrared detector data into an image that
can be viewed on the built-in OLED display. The image is observed
through an eyepiece by operator.
1.2.7. ELECTRICAL FUNCTION
The electronic circuit is powered by replaceable batteries - either
two 3.0 Volt lithium battery (CR123A).
Power from the batteries is supplied to the components through the
OFF-ON switch button.
