Subwindowing

Window Mode of ImageIR® – Up to 105,000 Hz

The ImageIR® can be operated in full, half, quarter and sub mode. With the camera control software, it is possible to use the extended subwindowing function. Using click-and-drag, freely definable sections can be set up quickly and conveniently. Subwindow image frequencies of up to 105,000 Hz can thus be achieved.

Over­view of Bene­fits of High-Speed-Ther­mo­graphy with ImageIR®

  • High-speed measurement up to 105,000 Hz

  • Snapshot detectors and complementary components provide for highest measurement speed

  • Fully radiometric real-time sequences with up to 16 bit data depth

  • Capture of extremely rapid temperature and motion sequences

  • High-speed capture of radiometric thermal images on Notebook/PC via 10 GigE interface

High-speed Meas­ure­ment with Vari­oCAM® High Defin­i­tion

The infrared camera VarioCAM® High Definition enables the usage of the sub-frame mode (sub-windowing) for rapid temperature changes. This means thermographic sequences with refresh rates of up to 240 Hz can be created with the camera series VarioCAM® HD. A defined sub-frame of the detector is picked out to achieve these extremely high refresh rates.

Besides the storage of thermographic sequences via GigE interface with the thermography software IRBIS® 3 online, there is the option to save fully radiometric sequences with 16 bit data depth directly in the camera memory, to analyse there or transmit to the software IRBIS® 3. No measurement information is lost with high-speed online measurement. Data can be analysed in detail and subsequently processes.

HighSense for thermographic camera series ImageIR®

High­Sense – Always the Optimal Camera Setting

Thanks to HighSense, ImageIR® users have the option of setting up individual measuring ranges based on the factory calibration that best suit the respective task. Depending on the measuring task, the required temperature range can be selected and the optimum integration time for this purpose is calculated – or one decides to proceed in reverse order. Thus, the calibration can be retained even in the case of changed integration times.

HDR – Simultaneous Mapping of Wide Temperature Ranges

The High Dynamic Range (HDR) function of the Infrared ImageIR® camera series enables measurement scenarios with extremely different temperatures to be recorded continuously. When recording in HDR mode, multiple thermograms with different integration times and different filters are recorded quickly in succession and compiled into an overall image with a high dynamic range. The measuring range can span up to 1,500 K. Users obtain high-contrast images in a wide temperature range characterized by high measurement accuracy.

MicroScan feature ImageIR

Micro­Scan – Quad­ruple the Image Format

Behind the function is a fast-rotating MicroScan wheel, which is integrated into the camera. It ensures that four different individual exposures are taken per wheel revolution, which are offset laterally by half a pixel each. In this way, thermography achieves a new quality due to thermal images providing a quadrupled spatial resolution.

Significantly extended temperature range using the MIT function

Multi Integration Time (MIT)

To measure temperatures spanning more than one calibration range requires the acquisition of multiple thermograms with different calibrations. This can be achieved by using our Multi Integration Time feature (MIT). This function increases the dynamic range up to 16 bit and significantly extends the temperature measurement ranges.
