Abstract: A sensitive method for detecting minute changes in apparently repetitive infrared signals in which infrared signals from repeated surface scans are processed by subtracting the signals representative of a scanning interval from signals representative of a subsequent scanning interval and differences resulting from a series of such subtractions are summed.
