c. Principle of Operation
the atn voyager is a hand-held night vision system that enables
walking, short-range surveillance and administering first aid in both
moonlight and starlight. the device can be also equipped with an
infrared light-emitting source.
Bi-ocular utilizes the principle of intensification of the residual light
which is reflected from the surrounding objects. the optical system
of the monocular consists of: an objective lens, an image intensifier
tube and two eyepieces.
D. Smart Digital Technology
Smart Digital technology finally provides for the user the total
control in the hi-tech industry of night vision. on-board computer
systems identify the user's intention of look through the bi-ocular.
When the bi-ocular is brought to the user's eyes, the bi-ocular will
automatically turn on. When removed from the eyes the bi-ocular
will turn off (you must engage the proximity Sensor for this feature
to work).
the user will never have to worry about turning his or her bi-ocular
on or off. Smart series bi-ocular automatically sense when they are
no longer used and shut off and enter their sleep mode.
even if your battery is low, don't worry the Smart Series will let warn
you with a light indicator in the Fov.
Color coded indicator in the Fov let you know the mode of opera-
tion you are using.
1. proximity Sensor Indicator - when the sensor is on, the indicator
in the Fov will light red.
2. Highlight Protective System Indicator - if the level of light expo-
sure exceeds allowable the indicator will lights green.
3. low Battery Indicator - when the battery is low the red indicator
in the Fov starts blinking.
E. automatic brightness control System
the device has a built in automatic Brightness Control. this control
automatically adjusts the brightness of image intensifier tube to the
optimal level.
