The MS-IR FAST infrared cameras (Figure 1) enable spectral signature analysis by splitting the scene signal into eight different spectral bands instead of only one broadband image. These fast frame rates, infrared cameras are equipped with a filter wheel fast-rotating mechanism in order to optimize the frame rate of the camera. The filter wheel can be used in both fixed and rotating modes.

Key Features and Advantages
The MS-IR FAST infrared cameras have multispectral capabilities, performing 8-channel multispectral analysis with the help of the high-speed filter wheel. With a user-selectable rotating speed of up to 100Hz, a frame rate of up to 800fps can be supported by the filter wheel. The acquisition of images is synchronized in fast rotating mode, thereby enabling the acquisition of one image per filter. The ultra-high frame rate of the MS-IR FAST infrared cameras allows an optimum data throughput of larger than 1 Gigapixel/s. With high-performance electronics, they generate full-frame thermal images at rates of up to 1500fps. It is possible to acquire sub-windows at rates higher than 35000fps.
The MS-IR FAST infrared cameras have high dynamic range and the unique Telops proprietary non-linearity correction and exposure time-independent calibration algorithms facilitate scene targets to be observed with the maximum possible accuracy and contrast. Fast automated attenuation filters are suitable for performing measurements of scenes with extreme temperature fluctuations.
Advanced calibration is another advantage of the FAST-IR infrared cameras. Their proprietary real-time infrared image processing includes enhanced high dynamic range imaging (EHDRI), automated exposure control (AEC), in-band radiance, radiometric temperature, and NUC. They have high sensitivity and are capable of detecting temperature differences down to 20mK. They yield accurate measurements with a radiometric temperature accuracy of ±1°C or ±1% over the entire range.
