A photonic approach to generate tunable microwave signal with frequency-multiplication is proposed. In the proposed scheme, the microwave signal with tunable fundamental frequency is generated by an optoelectronic oscillator (OEO) incorporating a tunable microwave photonic bandpass filter. Then a stimulated Brillouin scattering (SBS) assisted notch filter(More)
The study was aimed to evaluate the right ventricular function in pneumoconiosis patients by real-time three-dimensional echocardiography. A total of 80 individuals including 44 consecutive pneumoconiosis patients and 36 age- and gender-matched healthy volunteers as controls were prospectively recruited for the study. All the patients underwent two- and(More)
