Abstract: The present invention provides a method for extracting heat-sensitive Antarctic krill oil comprising the following steps. Firstly, frozen Antarctic krill is thawed and minced; a surfactant is added to the minced Antarctic krill to form a supercritical micelle system; extract the Antarctic krill multiple times after pressurizing and liquefying mixed gases; at the same time, a low-carbon alcohol solvent is added to strip the material in the critical micelle; after the extraction is completed, the extractant is removed; the extraction product and the residue after the extraction are subsequently collected; the heat-sensitive Antarctic krill oil can be obtained by high-speed centrifugal separation of the oil-water mixed extraction product. The present method has the advantages of simple operation, low extraction pressure and high safety. The extraction method of gas pressure liquefaction is completed under low temperature sealing conditions.

Abstract: A method for measuring the diameter of filament diffraction fringes by frequency domain calculation comprising: building a set of diffraction optical path measurement system and capturing diffraction fringe images; determining the starting point of the imaging range; Simulating the electromagnetic field propagation process in Fraunhofer diffraction, and determining the optimal fringe range considering the noise caused by the difference in CCD sensitivity; Finally calculating the filament diameter by Fourier transform for different lengths of fringe. The final value of the calculated filament diameter is obtained by fitting an envelope to the variation of the diameter. The invention is simple in calculation and has little dependence on the experimental device, which means the superiority of using the frequency domain for parameter measurement, and the measurement accuracy is in the sub-nanometer level. In addition, the invention proves the feasibility of extracting the fringe period information in the frequency domain.
