Multimodal imaging in biology plays an important role. So far the 3D visualization of fluorescence is realized by scanning systems. For faster imaging, the sectioning process intrinsically exhibits limitations in recording speed. We presented common-path off-axis incoherent digital holography using dual gratings on dual Fresnel lenses. Using the proposed method, single-shot, 3D fluorescence imaging...
Parallel phase-shifting digital holography (PPSDH) has been introduced. Movies of high-speed 3-D imaging and those of high-speed phase imaging obtained by PPSDH using a high-speed camera will be demonstrated at the presentation. PPSDH will contribute for 3-D measurement of moving object in such the applications as biological microscope, particle and flow measurement, and so on. This study was partially...
Fabrication methods of an artificial scattering medium with controlled scattering coefficient are presented. In the medium, there are many voids fabricated by focused femtosecond laser pulses. The number of voids randomly fabricated in a transparent medium can result in the change of scattering coefficient. We present experimental results of the fabrication of scattering media in polymers. We also...
An enlargement method of reconstruction angle by time-sharing tilted illumination in a three-dimensional (3D) display system based on wavefront modulation is presented. In a recording system, an array of phase-shifting interferometer is used for recording the wavefront data from 3D object in wide angle. In a reconstruction system, single display device such as spatial light modulator is illuminated...
