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...

Fast Fourier Transform

Fast Fourier Transform

The Fast Fourier Transform (FFT) is a computational algorithm designed to compute the Discrete Fourier Transform (DFT) efficiently. By breaking down the calculations into smaller, manageable sections, the FFT significantly reduces the computational complexity involved. Direct computation of an N-point DFT requires N2 complex multiplications, whereas the FFT algorithm needs only (N/2)log⁡2N multiplications, offering a much faster performance.
The computational efficiency of the FFT becomes...

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Deriving approximate wave pictures from exact solutions of circular and elliptic cylindrical invisibility cloaks.

Employing the L(2) norm to quantify the error between exact and approximate solutions.

Main Results:

The morphing algorithm achieves high accuracy (typically <2% L(2) norm error) for well-behaved cloak shapes when control points are optimized.
The approach successfully models cloak functionalities such as rotation and concentration, leading to the discovery of a 'rotacon' device.
The method shows limitations for 'superscatterers,' with errors around 25% in the L(2) norm.

Conclusions:

Morphing algorithms offer a significantly accelerated approach for numerical studies of 2D and 3D invisibility cloaks.
This method provides a valuable tool for exploring a wider range of cloak designs and functionalities.
Further research is needed to address the limitations for complex scattering scenarios like superscatterers.
