Real time spectroscopic imaging system and method |
摘要 |
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.
