Parallel optical-feature extraction by use of rotationally multiplexed holograms
Optics Letters
|November 3, 2009
Abstract:
We propose a novel rotational (peristrophic) multiplexing method of hologram recording for parallel opticalfeature extraction and report basic experimental results. The features to be extracted are line-segment orientations separated by 30 degrees . The extracted features can be used for f lexible pattern recognition.

Imaging Biological Samples with Optical Microscopy
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

Phase Contrast and Differential Interference Contrast Microscopy
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
