IRTIS-2000 ME Veterinary - computer camera-thermograph for thermal imaging

Irtis Vet-1

Computer thermography

Thermography - a method of visualization and registration of own infrared radiation of surface of the body, which allows detection of pathology, based on deviations of the temperature distribution over the surface of the body.

Any body whose temperature is above absolute zero (-273 degrees C) is a source of heat radiation - electromagnetic waves, emitted infrared waves contain information about members of the body structures (materials) with different temperatures and their location.

IRTIS-2000 ME Veterinary

IR-camera IRTIS-2000 МЕ is a precision optical-mechanical scanner with a highly sensitive IR-receiver.

A number of know-how used in the device allow to achieve high repeatability of measurements from frame to frame with uniform sensitivity across the frame and a high visualization of the object to be very close to reality.

This allows to make dynamic infrared shooting of the same area of the patient periodically, and then run over the thermograms obtained in the form of thermal footage. The configuration of the device is optimized for maximum achievement of high technical parameters, and the combination with the latest computer technology ensures high efficiency of the device for a wide range of tasks.

IRTIS-2000 ME is based on the experiments we gained during 30 years of research in the field of thermography with entering of mobility standard in systems of electric power, fuel, chemical and oil-production complexes, municipal services, development, medicine and other spheres.

Operation principle

The operation principle of IRTIS-2000 ME is based on scanning of thermal radiation in a field of view of a camera by an optic-mechanical scanner and a with single-element high repeatable IR-receiver with transformation of this radiation into an electrical signal by the analog-digital converter.

The camera has mirror-lens optics with a small number of reflecting surfaces, which minimizes losses of the optical system and simplifies its adjustment. This makes it possible to obtain a high repeatability of the geometry of successive frames and uniform sensitivity over the entire frame field.

High sensitivity and stable characteristics

The basic model of the camera is provided with an IR-receiver cooled by liquid nitrogen. This ensures a high sensitivity of the camera (better than 0,05 C) even when the camera operates at low temperatures in the 3-5 microns range, allows the parameters of the IR-receiver to be stabilized regardless of the ambient temperature, and provides for accurate measurement of absolute temperatures.

On request the camera may be provided with an IR-receiver with thermoelectric cooling.

The interface unit of the device is mounted inside the IR-scanner and can be connected to any computer through a parallel printer port without any supplementary equipments, what makes higher effectiveness and obtains a market improvement of system and makes it possible to upgrade the device (if a new computer elaboration and programs will be made).

The experience which we have gained during many years of reseach in the field of thermography indicates that for most practical applications it is enough to scan the frame for the 1-2 sec, because thermal processes of objects under investigation occur at much lower speed.

The real-time which determines the operating speed of the system depends not only on frame scanning speed but also on the time required to display and analyze the in formation and record the thermograms.

Examples of using in Veterinary Medicine

The use of thermography in veterinary medicine is one of the most effective methods of diagnosis, as is often the animal does not allow to touch it or carry out a detailed inspection by a veterinarian.
