    摘要: A method for analyzing mucosa structure with optical coherence tomography (OCT) is provided, and includes: (a) scanning a mucosa sample with optical coherence tomography; (b) choosing a lateral range from a two- or three-dimensional OCT image and analyzing all the A-scan intensity profiles in the lateral range; (c) calculating three indicators in each A-scan intensity profile, including the standard deviation for a certain depth range below the sample surface, the exponential decay constant of the spatial-frequency spectrum and the epithelium thickness under the condition that the basement membrane is identifiable; and (d) using the three indicators of each A-scan intensity profile within the lateral range to analyze the mucosa structure.

    摘要: Measurement system and methods for measuring oxygenated hemoglobin saturation level are provided. Light is transmitted to test blood and a reference mirror. The reference mirror provides a first reflected light beam, and backscattered light from different depths of the test blood generates a second reflected light beam. An interfered light signal is generated by light interference of the first and second reflected light beams. According to the interfered light signal, a first light decay constant for a first light wavelength range and a second light decay constant for a second light wavelength range are obtained according to the interfered light signal. A decay ratio of the first light decay constant to the second light decay constant is obtained. Oxygenated hemoglobin saturation level of the test blood is obtained according to the decay ratio.
