Abstract: The present invention relates to a Photoelastic Modulator (PEM), particularly to a novel polarized light modulator structure based on a photoelastic effect. The PEM, which controls driving voltages of two groups of piezoelectric actuators, is able to implement polarized light modulation having a relatively large optical path difference, and polarized light modulator having a fast modulation shaft moving circumferentially, and the PEM operates stably without a moving component. The present invention includes the piezoelectric actuators, a light pass crystal and a driver controller. Two light pass faces of the light pass crystal are parallel regular octagons directly facing each other, and identical rectangles are formed by side faces of the light pass crystal. The piezoelectric actuators are in soft connection with middle positions of the rectangles by connection rubber layers.

Abstract: A buoy-type high-frequency ground wave radar system. A buoy platform is used as an offshore carrier of a ground wave radar. A sky wave emission subsystem is disposed on a shore base and emits a high-frequency electromagnet wave. After the high-frequency electromagnet wave is refracted by the ionosphere and is reflected by the sea surface, a sky wave signal is formed. An attitude measurement subsystem measures and acquires attitude data of the buoy platform in real time. A ground wave radar subsystem receives a ground wave signal by using the ground wave radar, and processes the signal to form a ground wave doppler spectrum. Simultaneously, the sky wave signal is received, ionosphere disturbance compensation is performed on the sky wave signal in a frequency domain and then the sky wave signal is processed to form a sky wave doppler spectrum.

Abstract: The Invention relates to a method for preparing a multichannel hollow fiber membrane. According to a certain ratio, ceramic powder, a macromolecular polymer, an organic solvent, and a dispersant are mixed evenly to prepare a membrane casting solution; and after bubble removing processing is performed on the membrane casting solution, a membrane green body is formed with the cooperation of a multichannel hollow fiber die and phase inversion. After the membrane green body is roasted at a high temperature, a multichannel ceramic hollow fiber membrane is formed. The multichannel ceramic hollow fiber membrane has an asymmetric structure and a skeleton structure in an inner cavity and can meet the strength and flux requirements of a ceramic hollow fiber membrane.
