Abstract: To dramatically reduce image data processing requirements in spectroscopic imaging systems, an optical filter is alternatingly tuned to a pair of selected passband wavelengths related to an absorption wavelength of a sample under test, such that only light of the two selected wavelengths received from the test sample are recorded as alternating image frames by a CCD optical detector. Successive pairs of consecutive image frames are computer processed, on a corresponding pixel-by-pixel basis, to generate a series of composite image frames that may be displayed in enhanced contrast to permit real time analysis of a sample characteristic of interest.

Abstract: An airspace management system and method includes an alternate quick look mode display option which allows a user to designate a specific geographic region for display in a specified area on a display screen. Within this specified area, which can encompass a portion or all of the display screen, radar plot data is displayed for at least one aircraft for which input radar information is received. Symbols can be assigned to aircraft to differentiate friend and enemy aircraft; colors can be assigned to differentiate friend and enemy aircraft and plots; and radar-measured height information can optionally be displayed. In this quick look mode, near real-time positions for all aircraft within the quick look mode window are displayed, since selection of the quick look mode window bypasses normal time-consuming tracking information processing.
