Dual wavelength digital holographic Laplacian reconstruction.
Access to the spatial derivatives of an optical wave field can be used to enhance edge detection, focusing, and holographic imaging. It was recently shown that, by using digital holographic techniques, the Laplacian of an object field can be extracted. Here it is demonstrated that equivalent results can be found using two holograms captured at either two distances or with two appropriately rela...
متن کاملDigital holographic microscopy with dual-wavelength phase unwrapping.
We apply the techniques of digital holography to obtain microscopic three-dimensional images of biological cells. The optical system is capable of microscopic holography with diffraction-limited resolution by projecting a magnified image of a microscopic hologram plane onto a CCD plane. Two-wavelength phase-imaging digital holography is applied to produce unwrapped phase images of biological ce...
متن کاملDual-Channel Digital Holographic Imaging for Fingerprint Biometrics
We introduce a dual-channel, polarization-sensitive holographic phase imaging system for fingerprint biometrics. From two orthogonal polarization channels, we extracted fingerprint phase images, showing unique features that are detectable only in one of the polarization channels. OCIS codes: (090.1995) Digital Holography; (260.5430) Polarization.
متن کاملImproved tomographic imaging of wavelength scanning digital holographic microscopy by use of digital spectral shaping.
The technique of wavelength scanning digital holographic microscopy (WSDHM) is improved by use of a digital spectral shaping method which is used to suppress the sidelobes of the amplitude modulation function in WSDHM for non-Gaussian-shaped source spectra. Spurious structures caused by sidelobes can be eliminated in tomographic imaging and the performance of the tomographic system greatly impr...
متن کاملReal-time dual-wavelength digital holographic microscopy with a single hologram acquisition.
A technique to perform two-wavelengths digital holographic microscopy (DHM) measurements with a single hologram acquisition is presented. The vertical measurement range without phase ambiguity is extended to the micron-range, thanks to the resulting synthetic wavelength defined by the beating of two wavelengths with a separation of about 80nm. Real-time dual-wavelength imaging is made possible ...
