Key Features and Benefits
The ultra-high frame rate of the FAST-IR 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. 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. These unique features provide scientists with a user-friendly instrument with exceptional operational flexibility, providing accurate measurements over the entire operating range of the camera.
Unique Telops proprietary non-linearity correction and exposure time-independent calibration algorithms facilitate targets to be observed with the maximum possible accuracy and contrast. The FAST-IR infrared cameras provide radiometric temperature accuracy of ±1°C or ±1% over the entire range. They have high sensitivity and are capable of detecting temperature differences down to 20mK. Illustrative examples of dynamic events that can be analyzed using the FAST-IR infrared cameras are presented in Figures 3 and 4.
