Introduction to medium-wave cooled thermal imaging cameras

D-MC series medium-wave refrigeration red thermal imager adopts high-performance cadmium tellurium mercury detector, is the latest generation of standardized refrigeration movement of Xi'an Tellhow infrared, with high frame rate, high sensitivity, small size, easy integration and other characteristics, can work around the clock, in the total dark night and harsh conditions to generate clear infrared images, assist in the detection, search and tracking of targets. The product has complete functions, rich interfaces, high reliability and strong scalability, and can be integrated into various platforms and used in many related fields.

Application in photoelectric theodolite

Photoelectric theodolite plays an important role in aerospace, aviation and other fields, the use of photoelectric theodolite image data, can fully explore the hidden information in the target image, for the analysis, judgment, evaluation and verification of flight performance to provide objective data. The D-MC series medium-wave refrigeration products independently developed by Xi'an Tellhow IR have been used in theodolite in many domestic scientific research units, realizing the detection, identification and tracking of weak signal small targets under complex background conditions such as shooting ranges.

Application in airborne photoelectric pods

The D-MC series adopts a miniaturized design, the overall structure size covers the shape envelope of the detector, and the FPGA is used as the main core device implemented by the digital image processing algorithm, which has the characteristics of small size, low power consumption and high reliability. Now it has been applied to a variety of high-precision photoelectric pods, realizing high-altitude photography, video, ultra-long-distance target detection, recognition and other functions, combined with temperature measurement, ranging and tracking functions, can be widely used in anti-terrorism equipment, urban security, search and rescue, patrol law enforcement and other fields.

Application in vehicle-mounted photoelectric turrets

The high-sensitivity, high-reliability infrared thermal imager is the guarantee for a new generation of vehicle-mounted turrets to achieve long-distance detection, fast capture and high-precision tracking of targets. D-MC series medium-wave refrigeration thermal imager has been applied to a model of domestic vehicle-mounted photoelectric turret system, the product meets GJB vibration shock, sealing and moisture protection and other environmental requirements, imaging algorithm adopts multiple background non-uniformity automatic correction technology, to achieve automatic detection and identification of long-distance targets in various temperature scenes and complex environments, can be widely used in border sea protection, field investigation, forest fire prevention and other fields.
