DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Command consists of next primary parts: a body, a lens assembly and an eyepiece assembly. Figure
2-1 represents two versions of the equipment: one including a 50mm focal length objective lens, 75mm
focal length objective lens, and the other with a 100mm focal length objective lens.
The Command is a thermosensitive device. It senses the differences in heat emitted by objects in its field
of view, and converts the received temperature pattern into a viewable image that represents the scene
in contrasting black & white or color patterns, depending on the user’s selected image palette.
NOTE:
It is important that the Command sensor receive sufficient thermal contrast between the target
and background area, or between the different parts of a target. For example, the vast temperature
contrast between the snow and any heat target (such as an animal) makes it very easy to distinguish
the target.
The main optical-electronic components of the Command include: an objective Germanium thermal lens,
two eyepieces, a thermal-imaging camera, a display, a control card, and a button control panel.
The Command is equipped with manual eyepiece and objective lens focusing.
To accommodate individual user needs, the Command has a variety of digitally controlled options such as:
• Display Brightness
• Digital Zoom
