5ASP USER MANUAL
1 GENERAL INFORMATION
1.1 SYSTEM DESCRIPTION
The Asp 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 Asp sensor receive sufficient thermal contrast between the target and
background area, or between the different parts of a target. For example, there would be a vast
temperature contrast between the snow and any heat target (such as an animal), making it
exceptionally easy to distinguish the target.
The Asp consists of next primary parts: a body, a lens assembly and an eyepiece assembly. Figure
1-1 represents three versions of the device equiped with objective lenses with 25mm, 50mm, and
75mm focal length.
The main optical-electronic components of the Asp include: an objective Germanium thermal
lens, eyepiece, a thermal-imaging camera, a display, a control card, and a button control panel.
The Asp is equipped with manual eyepiece and objective lens focusing.
All Asp devices are based on FLIR Tau 2 cameras that allow for improvements in overall image
quality in a wide range of dynamic thermal environments.
To accommodate individual user needs, the Asp 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)
Information on the current operating state (battery status, active function in the display etc.) is
continuously displayed, making field operation of the Asp simple and convenient.
