PRODUCT DESCRIPTION AND PRINCIPLE OF OPERATION

The Python device allows detection of objects that emit energy in the infrared

spectrum. The equipment can operate in rain, fog and total darkness in a completely

passive mode (without additional illumination). The active matrix is microbolometer,

working in the wavelength range from 7 to 14 μm. The unique design of the device

makes it reliable and ergonomic.

The body is made of strong, ultra-lightweight magnesium alloy and has been applied

with matt anti-reflective coating. The device's functions can be accessed through the

buttons, while the OSD (on-screen-display) provides status information about it's cur-

rent condition.

The principle of operation of non-cooled system is illustrated schematically on the picture

below.

A special germanium objective lens focuses the infrared energy emitted by all of the

objects in field of view of the device. The focused radiation is scanned by an array

of infrared-detector elements. The detector elements create a detailed temperature

pattern of the observed scene called a thermogram. The signal generated by the

detector elements is passed through an analog-to-digital converter and translated

into discrete electric impulses. The impulses are sent to an image-processing unit, a

circuit board with a dedicated chip that improves the image quality and converts the

information from the elements into data for the display. The signal-processing unit

sends the information to the display, where it is displayed as a different shade of gray

depending on the intensity of the infrared emission. The combination of the impulses

from all of the detector's elements creates the final image.
