Digital in-line holographic microscopy.
We first briefly review the state of the art of digital in-line holographic microscopy (DIHM) with numerical reconstruction and then discuss some technical issues, such as lateral and depth resolution, depth of field, twin image, four-dimensional tracking, and reconstruction algorithm. We then present a host of examples from microfluidics and biology of tracking the motion of spheres, algae, an...
متن کاملDigital In-line Holographic Microscopy
Three-dimensional imaging with micron resolution and simultaneous tracking of many (hundreds) objects (bubbles, beads, algae, bacteria etc.) is now possiblein situ not only with a benchtop microscope, but also remotely in such environments as the deep ocean with a submersible version of the instrument. The instrument is very simple in its hardware requirements and an efficient software package ...
متن کاملIn-line digital holographic microscopy using a consumer scanner
We demonstrate an in-line digital holographic microscopy using a consumer scanner. The consumer scanner can scan an image with 4,800 dpi. The pixel pitch is approximately 5.29 μm. The system using a consumer scanner has a simple structure, compared with synthetic aperture digital holography using a camera mounted on a two-dimensional moving stage. In this demonstration, we captured an in-line h...

We focus on the two most widely used Fresnel approximation algorithms, the direct method and...
متن کاملMicropipe flow visualization using digital in-line holographic microscopy.
Digital in-line holography is used to visualize particle motion within a cylindrical micropipe. Analytical expression of the intensity distribution recorded in the CCD sensor plane is derived using the generalized Huygens-Fresnel integral associated with the ABCD matrices formalism. Holograms obtained in a 100microm in diameter micropipe are then reconstructed using fractional Fourier transform...
