1. Calculate the radiant flux of a human being with a temperature of 97 F degree. Assume that human has an emissivity of 0.99.
2. What are the two major atmospheric windows for thermal infrared remote sensing? (hint, range of wavelength)
3. What is the wavelength of maximum spectral radiant exitance for the moon (- 173°C), the Mars (- 125°C) and a human being (37 C degree)?
4. A thermal infrared thermometer is used to measure the temperature of an object. The setting of emissivity on the thermal infrared thermometer is 0.98. The temperature reading shows 30 C degree. What will be the temperature reading for the same object if you accidently change the emissivity setting on the thermal infrared thermometer to 0.95?
5. Assume that an object is opaque and does not transmit radiation, its reflectance in 8-14 µm is 0.2. How much is the object's emissivity in 8-14 µm?
6. There are two major types of detector for thermal infrared camera. Cooled and uncooled. What are the differences between the two types of detector?
7. What is the spatial resolution, detector type, NETD, range of wavelength for the model of thermal infrared camera (FLIR T650SC)?
8. Give the geometric calibration equations using the five distortion coefficients.
9. What is purpose of image warping and Mosaicking in remote sensing?
10. What is emissivity?
