Multi Integration Time (MIT) and its Advantages

Due to the binning technology, infrared cameras have two speed modes – the standard mode and the high-speed mode, in which the frame rate increases more than three times. The field of view remains constant in both modes, so the scene captured by the camera does not change. In high-speed mode, the thermal resolution also increases by a factor of two.

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.

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.

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.

The thermal imaging camera 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. A defined sub-frame of the detector is picked out to achieve these extremely high refresh rates.

The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.
