Custom Thermal Imaging

Jan. 3, 2019
Infratec's infrared camera allows a user to adjust the settings every time, for optimal measurement accuracy.

Different measurement scenarios often require temperature measurement ranges or integration times that vary from the initial factory calibration and are individually adjusted. Usually the calibration is invalid because of such adjustments and the thermographic camera no longer provides any accurate temperature measurements. Such a massive restriction does not apply to users of the ImageIR thermographic camera series. Thanks to the innovative HighSense function, the measurement accuracy of their cameras is also preserved when integration times or the measurement ranges are changed. With maximum flexibility they also save costs, for example, by avoiding additional application-specific special calibrations.

 

The development enhances the existing factory calibration of the thermographic camera. It enables the possibility of setting up individual customized temperature measurement ranges. Users can apply their specific settings in different ways.

 

The first way allows for the selection of a desired integration time. After entering the integration time via the intuitive software interface, the resulting temperature measurement range is calculated automatically and can be used for accurate measurements. At the same time, the selected lens as well as neutral density filters or spectral filters are also considered.

 

The second way addresses the issue of the temperature measurement range. This can be specified by defining an upper and lower limit. Afterwards, the appropriate integration time is calculated again to achieve the optimum signal-to-noise ratio and stored as setting parameter for the planned measurement task. Depending on whether a particularly high thermal sensitivity or the maximum possible frame rate is paramount – with the appropriate adjustment of integration times and the resultant automatically generated temperature measurement ranges the HighSense feature offers considerably more flexibility to optimally fulfill the measuring tasks at hand.

 

In addition, the calibration of individual sub-frames is no longer necessary. The adjustment of the calibration data, which applies to these frames, takes place automatically as well. On this basis, accurate temperature measurement values are also provided for the corresponding window modes. Thus, the choice of the temperature measurement range as well as the integration time does not depend on whether the image should result in full-frame mode or in sub-frame mode, which can be used to achieve a higher frame rate.

 

Thanks to HighSense, users of the ImageIR now have the option to set up individual measurement ranges based on the factory calibration, which are best suited to the task at hand. The software also offers the possibility of storing a multitude of such ranges in a clearly visible way. Individually named and permanently stored, the user can access these settings quickly. The same holds true when it comes to changing, renaming, and deleting the profiles.

 

HighSense is available for various camera models of the ImageIR series. Systems that have already been delivered can optionally be enhanced by this function.
