Fischer Projections

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Color Vision

Color Vision

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Phase Contrast and Differential Interference Contrast Microscopy

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...

Background:

Traditional 3-D imaging often struggles with full-color reproduction.
Reconstructing three-dimensional (3-D) objects from projections is a complex challenge.

Main Methods:

A novel method utilizing white light projection and a color-Charge-Coupled Device (CCD) camera was employed.
Three-dimensional (3-D) Fourier spectra were calculated separately for red, green, and blue color information from projection images.
Computer-generated holograms (CGHs) were synthesized from the obtained 3-D Fourier spectra.

Main Results:

Full-color three-dimensional (3-D) information was successfully extracted from projection images.
Computer-generated holograms (CGHs) were synthesized, enabling image reconstruction.
