In our previous published research we have studied the applications of ferrolens for observation and qualitative analysis non-homogeneous magnetic fields. Latest developments over last few years increased multifold sensitivity this device allowing it to display fields as low 10mT in strength therefore is possible now observe also homogeneous (i.e. straight parallel flux lines uniform density sp...

Color metasurface holograms are powerful and versatile platforms for modulating the amplitude, phase, polarization, other properties of light at multiple operating wavelengths. However, current color holography can only realize static manipulation. In this study, we propose demonstrate a multiplexing technique combined with multiwavelength code-division (CDM) to dynamic Multicolor code referenc...
