A method and a system for detecting and analyzing a mucosa of a digestive tract are provided. The method includes detecting reply signals from the mucosa of the digestive tract within a depth range, acquiring 2D vascular images by performing a vascular enhancement on the reply signals, constructing a 3D vascular contrasting image of at least part of the mucosa of the digestive tract within the depth range by recombining at least part of the 2D vascular images, and reconstructing a 3D vascular contrasting projection image by performing a projection process to the 3D vascular contrasting image, and defining a stage of the mucosa of the digestive tract within the depth range according to the 3D vascular contrasting projection image, the 3D vascular contrasting image, the 2D vascular images, and vessel morphologies shown therein.

The present invention provides a method of obtaining a classification boundary, to limit an axial depth in a puncturing operation. The following steps of method comprises: At first, obtaining a plurality of tomographic images from the axial depth of a tissue is performed. Then, obtaining a plurality of characteristic values from the tomographic images, the characteristic values are classified by a Support Vector Machine method. A classification boundary will be obtained through a distribution of the graph for defining a specific compartment of the tissue. In addition, an automatic recognition method and system using the above mentioned method are also disclosed in the present invention.

In an optical heterodyne surface plasma wave detecting method and apparatus, light that contains correlated Pand Pwave components (TM waves) is directed to a total reflective component such that two surface plasma waves are generated at an interface of a metal film and a test object. Light reflected from the total reflective component is detected to obtain an optical heterodyne test signal that is compared with an optical heterodyne reference signal to determine changes in at least one of amplitude and phase of the optical heterodyne signal relative to the optical heterodyne reference signal.

The present invention relates to a magic egg, which mainly comprises a hollow egg-like membrane having the color of egg white, and features of contractibility and stickiness, and besides, an opening is set at the top portion to let the diaphanous liquid and the yellow ball pass through and enter the egg-like membrane to bulge it, making it like an elliptic egg. In addition, a cover is combined with the opening of the egg-like membrane to enclose the opening steadily so that the diaphanous liquid can be prevented from effusion. When the user exert himself to cast the egg-like membrane having the diaphanous liquid and the yellow ball toward an plane, the egg-like membrane can adhere to the plane in a flat status like a fried egg. After a period, the egg-like membrane slowly recovers to the original elliptic egg style because of its contractibility.

In an optical rotation angle polarimeter for investigating optical activity of a test object, a two-frequency laser source generates a laser beam with two eigen modes of two different temporal frequencies and two orthogonal linear polarized waves. The laser beam is to be passed through the test object. The polarized beam splitter is adapted to receive and split the laser beam, which exits the test object, into first and second orthogonal optical heterodyne interference X-axis and Y-axis components. Each of first and second photo detectors receives a respective one of the first and second orthogonal optical heterodyne interference X-axis and Y-axis components from the polarized beam splitter, and generates a corresponding optical heterodyne interference signal. A signal processor is connected to the first and second photo detectors, and combines the optical heterodyne interference signals therefrom so as to obtain an optical heterodyne interference output. An amplitude detector detects the amplitude of the optical heterodyne interference output, which serves as a measure of the optical activity of the test object. In addition, the laser beam has an adjustable wavelength to permit measurement of dispersion of optical rotation angles versus wavelength for an optically active material or substance.
