Abstract: The invention provides an atrial fibrillation risk prediction system based on heartbeat rhythm signals. A heartbeat rhythm signal preprocessing module obtains heartbeat interval sequence data by calculating the time interval of two adjacent heartbeats. During sample labeling, a positive sample is from heartbeat interval data during the sinus heart rate period of a case with high AF risk, and a negative sample is from heartbeat interval data of a case with low AF risk; and an atrial fibrillation risk prediction model is trained with positive and negative samples and is used to test heartbeat interval data, an AF risk curve between the proportion of positive samples and output probability thresholds is obtained according to the output probabilities of testing samples, the area under the AF risk curve is calculated as the atrial fibrillation risk value, and the value can reflect the atrial fibrillation risk.

Abstract: A holographic wavefront printing system and method are provided. A two-dimension digital blazed grating is loaded on a phase hologram, and the emergent direction of active region diffracted light is adjusted to prevent overlapping with the dead region diffracted light after being Fourier transformed by a lens, and a phase spatial light modulator is inclined by a preset angle to change the emergent direction of the diffracted light, such that the dead region zeroth-order and first-order diffracted light on a focusing surface are symmetrical with respect to a main optical axis of a first lens, the frequency spectrum center of active region zeroth-order diffracted light is then loaded to the original frequency spectrum center without information change. In this way, the adverse effects of the dead region diffracted light and active region high-order diffracted light of the phase spatial light modulator on holographic wavefront printing are eliminated.

Abstract: A nonlinear optical device includes two coupling systems. A coupling coefficient between the two coupling systems is regulated and controlled. During operation, the pump light input from a straight waveguide is coupled into the second coupling system through the first coupling system and obtains great resonance enhancement in the second coupling system, so it is ensured that the second coupling system is in a high energy state. For signal light input from the same end of the straight waveguide, the signal light enters a resonator of the second coupling system through the coupling between the first and second coupling systems. A nonlinear effect of the system mainly occurs in the resonator of the second coupling system because in the resonator of the second coupling system, the pump light is in a great resonance enhancement. The entire resonator is in a high energy state.
