High-speed channel demixing by scanning interferometric focusing with binary transmission matrix

چکیده
In this paper, we demonstrate a fast binary intensity modulation based on the measurement of the binary TM. For each correction, the binary TM was calculated based on measurements of the intensity change at the target with a series of input masks. After preloading the measurement masks, the DMD can run at full speed during measurement. The system allows dynamic focusing at 12.5 Hz with 1024 input modes, and more than 60 times intensity enhancement. We demonstrate focusing light through a highly dynamic scattering sample, a live drosophila embryo.

High-speed scanning interferometric focusing by fast measurement of binary transmission matrix for channel demixing.
Using the fast measurement of a binary transmission matrix and a digital micromirror device, we demonstrate high-speed interferometric focusing through highly dynamic scattering media with binary intensity modulation. The scanning of speckles for reference optimization gives stable focusing, which can be used for focusing through a fast changing media or two dimensional scanning through a slowl...

In this paper, we improve the performance of the TiR-UWB communication systems with the non-ideal estimation of the channel. Time Reversal (TiR) technique is an effective and simple method for data transmission in extremely multipath indoor UWB channels that mitigates the complexity of receiver by its own time focusing feature. Although, TiR method has the suitable performance, but it is sensit...
