Light Acquisition02:16

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

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...
Imaging Biological Samples with Optical Microscopy01:18

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.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

    Area of Science:

    • Optical engineering
    • Astronomy instrumentation

    Background:

    • Adaptive optics (AO) systems are crucial for overcoming atmospheric turbulence.
    • Previous AO experiments often lack deterministic turbulence generation and integrated science cameras.

    Purpose of the Study:

    • To present results from a laboratory multiconjugate adaptive optics (MCAO) experiment.
    • To highlight the unique features of a programmable deterministic turbulence generator and an output science camera.

    Main Methods:

    • Turbulence was simulated using a dual-layer turbulence emulator.
    • A Shack-Hartman wavefront sensor processed information from five artificial guide stars.
    • An AO system with two wavefront correctors was employed for turbulence correction.

    Main Results:

    • The MCAO system demonstrated its capability to correct deterministic, programmable turbulence.
    • The experimental setup allowed for direct imaging and analysis of corrected wavefronts.

    Conclusions:

    • The developed experimental setup provides a valuable platform for testing and advancing MCAO systems.
    • The integration of a deterministic turbulence generator and science camera offers new possibilities for AO research.
