A system simulates hyperspectral imaging data or multispectral imaging data for a simulated sensor. Blackbody radiance of real-world thermal imagery data is computed using a Planck function, which generates a simulated spectral hypercube. Spectral emissivity data for background materials are multiplied by a per-pixel weighting function, which generates weighted spectral emissivity data. The simulated spectral hypercube is multiplied by the weighted spectral emissivity data, which generates background data in the simulated spectral hypercube. Simulated targets are inserted the background data using the Planck function. The simulated spectral hypercube is modified, and then it is used to estimate a mission measure of effectiveness of the simulated sensor.

A thermometry apparatus used during hyperthermia therapy, which has a mat that can be used in combination with a non-invasive thermometry system. The mat has a top face and a bottom face. Between the top face and the bottom face are embedded wires. The wires provide skin and treatment head thermal information based on the thermal coefficient of resistance of the wires or via two metals in a thermocouple configuration. The mat is placed between the skin and an ultrasound head. The mat is flexible enough to conform to the patient’s body shape at the treatment point. The mat may be used in combination with an infrared camera, where at least one IR camera is pointed at a semi perpendicular angle to the mat, whereby the IR camera measures the temperature directly from the mat side and continually below the ultrasound head providing thermal depth measurements.

A shutter operation state monitoring method performed in a thermal imaging camera includes, controlling a shutter of the thermal imaging camera to be closed, capturing a first thermal image, calculating a correction offset value for the first thermal image, controlling the shutter to be opened, capturing a second thermal image, applying the correction offset value to the second thermal image, measuring a sound with a microphone when controlling the shutter to be closed and/or when controlling the shutter to be opened, determining whether the measured sound matches an operation sound of the shutter, and outputting an alarm indicating malfunction of the shutter if the measured sound does not match the operation sound.
