Fischer Projections02:18

Fischer Projections

18.1K
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.

Newman Projections

24.6K
Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

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...

Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

1.3K
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Geometry of Hyperbolas01:30

Geometry of Hyperbolas

669
A hyperbola consists of all points where the absolute difference of distances to two fixed points, called foci, remains constant. The standard equation isEach branch extends infinitely and approaches two asymptotes, which guide the curve’s behavior. The parameters a and b define key features: a measures the distance from the center to each vertex along the transverse axis, while b influences the slopes of the asymptotes. The asymptotes have equationsA rectangle centered at the origin with...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

    Summary

    We developed a new algorithm to create holograms that can project complex patterns even through optical systems with significant aberrations. This method improves reconstruction accuracy for aberrated Fourier systems.

    Area of Science:

    • Optics and Photonics
    • Computational Imaging
    • Holography

    Background:

    • Optical reconstruction systems often suffer from field-dependent aberrations, degrading the quality of projected patterns.
    • Accurate projection of arbitrary patterns is crucial for applications in imaging and optical manipulation.

    Purpose of the Study:

    • To present a novel algorithm for computing computer-generated holograms (CGHs) capable of correcting strong field-dependent aberrations.
    • To enable the projection of arbitrary patterns through aberrated optical systems with high fidelity.

    Main Methods:

    • The algorithm modifies the iterative Fourier transform algorithm (IFTA).
    • Aberrations are precisely defined using Zernike polynomials.
    • A tunable constant allows adjustment of the trade-off between reconstruction error and diffraction efficiency.

    • The proposed modified IFTA algorithm is effective for generating holograms that compensate for significant field-dependent aberrations.
    • This work provides a practical solution for high-quality holographic projection in challenging optical environments.
    • The experimental results confirm the algorithm's capability to correct aberrations in Fourier-based optical systems.
