USER MANUAL
1 GENERAL INFORMATION
1.1 SYSTEM DESCRIPTION
The Cobra consists of next primary parts: a body, a lens assembly and an eyepiece assembly.
Figure 1-1 represents two versions of the equipment: one including a 50 mm focal length objective
lens, and the other with a 75 mm focal length objective lens.
The Cobra 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 Cobra 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 Cobra include: an objective Germanium thermal
lens, two eyepieces, a thermal-imaging camera, a display, a control card, and a button control
panel.
The Cobra is equipped with manual eyepiece and objective lens focusing.
To accommodate individual user needs, the Cobra has a variety of digitally controlled options
such as:
•
Display Brightness
•
Digital Zoom
•
Palette Color Selection
•
User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC)
•
Imaging Enhancements
•
