Abstract: The invention belongs to the technical field of OCT and provides an OCT image processing device and system. An FPGA is in communication connection with an upper computer via a PCIE interface to receive OCT image data acquired by the upper computer and to carry out image preprocessing on the OCT image data and then send the OCT image data to the upper computer to display. The OCT image data is acquired and displayed by the upper computer and the OCT image data's preprocessing is implemented by the FPGA, so that the processing efficiency of the OCT image data is greatly improved.

Abstract: UGC material transmitted by a user is received and stored in a material database. An index of the UGC material and a corresponding sample of the UGC material are established and stored. The index of the UGC material is stored in an account of the user. After an instruction for posting UGC is received from a user, according to indexes of UGC materials in the account of the user, samples of the UGC materials are called and displayed. A sample of a UGC material selected by the user and UGC elements currently input by the user are received. Corresponding UGC material is read from the material database according to the sample of the UGC material, read UGC material, and UGC elements currently input by the user are combined into UGC, and the UGC is posted.

Abstract: A fiber-inline MZI device for temperature sensing or refractive index (RI) sensing, the device comprising: a section of a Photonic Crystal Fiber (PCF) having at least two air holes infiltrated with a liquid analyte to form a waveguide channel, the liquid analyte forming rods in the PCF; wherein the rods leave an interference fringe pattern in the transmission spectrum when light is injected into the PCF, and fringe dips are tracked over a wide wavelength range in order to sense the temperature or refractive index.

Abstract: A single fiber Mach-Zehnder interferometer comprises an optical fiber having a core region and a cladding surrounding the core region, and a micro-cavity having part of the cladding and the core region removed, wherein the micro-cavity is adapted to receive a light beam and separate the light beam into a first light beam that propagates through the micro-cavity in an unguided mode, and a second light beam that propagates through the core region in a guided mode.
