Abstract: A method of detecting variance by regression model has the following steps. Step 1 is preparing the FDC data and WAT data for analysis. Step 2 is figuring out what latent variable effect of WAT data by Factor Analysis Step 3 is utilizing Principal Component Analysis to reduce the number of FDC variables to a few independent principal components. Step 4 is demonstrating how the tools and FDC data affect WAT data by Analysis of covariance model, and constructing interrelationship among FDC, WAT and tools. The interrelationship can point out which parameter effect WAT significantly. By the method, when WAT abnormal situation happened, it is easier for engineers to trace where the problem is.

Abstract: A microbolometer comprises an array of sensor elements or ‘pixels’ each individually responsive to generate an output indicative of the intensity of infrared radiation incident thereupon. In practice there are significant non-uniformities in the response of each pixel and further processing of the outputs must take place to generate an accurate image. These non-uniformities are dealt with by means of individual correction factors to be applied to the outputs of each pixel in the image. Commonly, the correction used provides a constant offset (1pt) and a linear gain correction (2pt). As the optimal values of these corrections drifts over time it is still necessary to provide further correction.

It is automatically determined, during in-the-field use, when the device is in a motionless state, and the output of the temperature and gyro sensors are read. The read gyro output is written to the lookup table as part of a pair of associated temperature and zero turn rate offset correction values. Other embodiments are also described and claimed.
