Abstract: This paper estimates the upper and lower bounds of theframe noise of a linear detector array that uses aone-dimensional scan pattern. Using chi-squaredistribution, it is analytically shown why it isnecessary to use the average of the variances and notthe average of the standard deviations to estimatethese bounds. Also, a criteria for determining whetherany excessively noisy lines exist among the detectorsis derived from these bounds. Using a Gaussian standardrandom variable generator, these bounds aredemonstrated to be accurate within the specifiedconfidence interval. A silicon detector array is thenused for actual dark current measurements. Thecriterion developed for determination of noisydetectors is checked on the experimentally obtaineddata.!2
