Imaging Biological Samples with Optical Microscopy

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...

Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Focusing of Light in the Eye

Focusing 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...

Area of Science:

Optics and Photonics
Materials Science

Background:

Transformation optics enables novel electromagnetic functionalities but faces challenges with material realization due to inherent mismatches.
Existing methods like generalized Snell's law can introduce phase discontinuities, limiting performance.

Purpose of the Study:

To introduce a novel Mirrored Transformation Optics (MTO) approach to address material mismatch issues in transformation optics.
To design and demonstrate a high-performance planar focusing lens using the MTO approach.

Main Methods:

The MTO approach leverages reflection principles by introducing a mirrored medium to compensate for phase discontinuities.
A transmission-type planar focusing lens was designed based on the MTO framework.

Main Results:

The designed MTO lens exhibits a larger concentration ratio compared to lenses designed using the generalized Snell's law.
The MTO approach preserves the original lens functionality while mitigating material constraints.

Conclusions:

The MTO approach offers a viable solution for overcoming material limitations in transformation optics.
The developed MTO planar lens shows significant potential for advanced applications in optical imaging and light energy harvesting.
