Published on: August 4, 2018
Summary
Forward optical glory effects in Mie scattering were observed for the first time. These phenomena, linked to surface waves, manifest as oscillations in efficiency factors and polarization deviations, detectable through proposed experiments.
Area of Science:
- Optics and Photonics
- Scattering Theory
Background:
- Mie scattering describes light interaction with spherical particles.
- Optical glories are typically observed in the backscattering direction.
Purpose of the Study:
- To report the first observation of forward optical glory effects in Mie scattering.
- To investigate the characteristics and underlying physics of these forward glory phenomena.
Main Methods:
- Theoretical analysis using complex angular momentum theory.
- Numerical simulations of Mie scattering efficiency factors and polarization.
Main Results:
- Observed regular oscillations in Mie efficiency factors in forward scattering.
- Identified characteristic deviations from zero polarization in near-forward scattering for specific refractive indices (√2 and 2).
- Complex angular momentum theory accurately predicted oscillation periods and highlighted the role of surface waves.
Conclusions:
- Forward optical glories are a novel observable phenomenon in Mie scattering.
- Surface waves play a crucial role in the generation of forward glories.
- Experimental detection is feasible through measurements of extinction, radiation pressure, and polarization.

01:18Imaging 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.

01:16Focusing of Light in the Eye
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...
02:16Light 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.
01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:16Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
