Abstract: | Real-time measurement of temperature field can be achieved by colorimetric method using ICCD as sensor. However, due to limited
dynamic response range of the ICCD, the measurable range of temperature is very small. In order to expand the temperature
measuring range, a device was developed which can take several two-color images with different shutoff times subsequently
within very short time. First, the principle of real-time measurement of temperature field with two-color thermal images is
introduced. Then theoretical analysis on this method, including determination of various parameters, such as shutoff time,
number of temperature range, wavelength of the colors, etc. is described. Experiments were conducted, which proved that theoretical
analysis coincides with the experimental results.
