The purpose of this study is to develop the thermal imaging system applying a two-color thermometry that is capable of producing a real-time-thermal-image of objects without assigning the emissivities data of the objects to the system, which was proposed by one of the investigator. The thermal imaging system has been designed and constructed in this study in order to reveal what problems we should solve for practical use.The system constructed in this study has a couple of 16-ch.-InSb-sensor-arrays with amplifiers and a dichroic half-mirror that can divide the detectable wavelength range of the InSb sensor (2.5 - 5.4 fim) into two ranges. The radiation at longer wavelengths (λ > 4.5 μm, λ is wavelength) are reflected by the mirror and the others are transmitted through the mirror. The divided radiation are derived into each sensor-array and measured simultaneously. The system has also an optical scanning system to produce a 2-dimensional image and Digital Signal Processor (DSP) to calc … More ulate the temperatures of objects from the measured radiation data.The system constructed in this study has a couple of 16-ch.-InSb-sensor-arrays with amplifiers and a dichroic half-mirror that can divide the detectable wavelength range of the InSb sensor (2.5 - 5.4 fim) into two ranges.

The system has also an optical scanning system to produce a 2-dimensional image and Digital Signal Processor (DSP) to calculate the temperatures of objects from the measured radiation data.The system works on measuring radiation emitted from objects and DSP can calculate the temperature from the measured radiation data. Since the controlling system that is required for the whole system is now developing, the system has not been completed yet. However, in this study, it has been clarified DSP is capable of producing a real-time-thermal-image, and the amplifier system improving signal-noise ratio has been developed. The whole system will be completed. Less
