6. A detector is used to measure the thermal radiation difference in Question 5 above. The detector has a surface area of 0.01 cm², a detectivity of 1 x 10² cm Hz¹/2/W, and a modulation frequency bandwidth of 1 Hz. The detector is 1.5 m away from both the object and the background. Estimate the maximal signal to noise ratio if you assume that the transmittance of the air is 100% between the object and the detector.

3. Use the MS Excel software to show that the numerical computation of the thermal radiation in the LW: 8-14 um by an object is 14 x 10+ W approximately, if the object's surface area is 1 cm², the object temperature is 300 K, and the object emissivity is 0.5. 4. Use the MS Excel software to show the numerical computation for the background at temperature of 283 K, with other conditions being the same as those in Question 3 above. 5. Refer to Questions 3 and 4 above, calculate the thermal radiation difference between the object and the background. 6. A detector is used to measure the thermal radiation difference in Question 5 above. The detector has a surface area of 0.01 cm², a detectivity of 1 x 10° cm Hz¹/2/W, and a modulation frequency bandwidth of 1 Hz. The detector is 1.5 m away from both the object and the background. Estimate the maximal signal to noise ratio if you assume that the transmittance of the air is 100% between the object and the detector.
