Abstract: The fringe analysis method, using phase modulation with wavelength tuning, is widely used in profiling the surfaces and thickness variation in optical flat interferometry. However, the ...

Abstract: In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited ...

Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

The MN88473 is a digital TV demodulator for DVB-T2/T/C reception. The demodulator has a built-in ADC and de-interleave memory. It has a Low-IF input and outputs TS serial/ parallel. MN88473 is ...
