A model of sub-wavelength metallic grating without host media is proposed. Under the excitation of TE polarized light, the extraordinary transmission is also found, and their transmission energy distributions corresponding to different structural paramete
Fresnel incoherent correlation holography (FINCH) is a self-interference based super-resolution three-dimensional imaging technique. FINCH in inline configuration requires an active phase modulator to record at least three phase-shifted camera shots to re
In the fiber optical synthetic aperture (FOSA) system, the diffraction of the Gaussian beam limited by the aperture in exit pupil plane of fiber collimator is studied theoretically, and the axial and transverse irradiance distributions are obtained. The p
