Digital in-line holography

H.]. Kreuzer and R.A. Pawlitzek" 'Department ofPhysics, Dalhousie University, Halifax, Canada "IBM Zurich Research Laboratory, Switzerland out by larger objects, classical diffraction becomes more important. When it eventually dominates the image,we are in the regime of classical wave optics. A hologram is just a complicated interference pattern from which little information about the shape and...

Single channel in-line multimodal digital holography.

We present a new single channel in-line setup for holographic recording that can properly record various objects that cannot be recorded by the Gabor holographic method. This configuration allows the recording of holograms based on several modalities while addressing important issues of the original Gabor setup, including the well-known twin-image problem and the weak scattering condition.

Digital in-line holography for biological applications.

Digital in-line holography with numerical reconstruction has been developed into a new tool, specifically for biological applications, that routinely achieves both lateral and depth resolution, at least at the micron level, in three-dimensional imaging. The experimental and numerical procedures have been incorporated into a program package with a very fast reconstruction algorithm that is now c...

Phase signature for particle detection with digital in-line holography.

The spatial phase resulting from the digital reconstruction of an in-line hologram of a particle field is shown to yield a unique pattern that can be used for particle detection. This phase signature is present only when viewed along with the reference light. The existence of the phase pattern is verified computationally and confirmed in laboratory experiments with holograms of calibrated glass...
