Depth resolution enhancement in double-detection optical scanning holography
(Optical Society of America, 2013-05-01)
We propose an optical scanning holography system with enhanced axial resolution using two detections at different depths. By scanning the object twice, we can obtain two different sets of Fresnel zone plates to sample the ...
Solving inverse problems for optical scanning holography using an adaptively iterative shrinkage-thresholding algorithm
(Optical Society of America, 2012-03-01)
Optical scanning holography (OSH) records a three-dimensional object into a two-dimensional hologram through two-dimensional optical scanning. The recovery of sectional images from the hologram, termed as an inverse problem, ...
Comparison of two-, three-, and four-exposure quadrature phase-shifting holography
(Optical Society of America, 2011-06-01)
In standard (four-exposure) quadrature phase-shifting holography (QPSH), two holograms and two intensity maps are acquired for zero-order-free and twin-image-free reconstruction. The measurement of the intensity map of the ...
Depth resolution enhancement in optical scanning holography with a dual-wavelength laser source
(Optical Society of America, 2011-12-01)
In this paper, we use two point sources to analyze the depth resolution of an optical scanning holography (OSH) system with a single-wavelength source. A dual-wavelength source is then employed to improve it, where this ...
