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...

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...

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...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Background:

Complex spectral optical coherence tomography (OCT) is an advanced imaging modality.
Traditional OCT methods face limitations in imaging depth and image quality due to noise.
Reconstructing both amplitude and phase is crucial for overcoming these limitations.

Purpose of the Study:

To introduce a novel implementation of complex spectral OCT for biomedical imaging.
To demonstrate the capability of this technique in imaging objects with considerable thickness.
To highlight the simultaneous use of phase and amplitude for enhanced spectral imaging systems.

Main Methods:

Implemented complex spectral OCT by reconstructing both amplitude and phase information.
Utilized negative and positive optical path differences for extended imaging range.
Applied noise reduction techniques to improve image quality.

Main Results:

Successfully imaged objects of considerable thickness by leveraging both amplitude and phase data.
Achieved significant reduction in coherent noise, leading to improved image quality.
Demonstrated an increased measurement range and simultaneous phase/amplitude utilization, a previously undescribed capability.

Conclusions:

The new complex spectral OCT implementation offers superior imaging of thick biological tissues.
This technique enhances image quality by reducing coherent noise and extending the measurement range.
The ability to simultaneously use phase and amplitude in spectral systems represents a significant advancement in OCT technology.
