Transmissive optical components tend to be classified as either diffractive or refractive, based on which phenomenon more accurately describes the way they function. Although their optical functions are governed by distinct physical phenomena, Fresne

Virtual reality and augmented reality devices require increasingly demanding optical components. Head mounted displays for VR systems often use molded Fresnel lenses, which can be affordably mass produced, maintain low weight, and still achieve high

Intraoperative margin assessment to evaluate resected tissue margins for neoplastic tissue is performed to prevent reoperations following breast-conserving surgery. High resolution microendoscopy (HRME) can rapidly acquire images of fresh tissue spec

Electro-Chemical Polishing is routinely used in the anodizing industry to achieve specular surface finishes of various metals products prior to anodizing. Electro-Chemical polishing functions by leveling the microscopic peaks and valleys of the subst

Advances in freeform optics, particularly fabrication, allow for the creation of new lenses. Four freeforms are described and fabricated: an atoric lens; a Zernike surface; an elliptical, anamorphic Fresnel lens; and a sinusoidal spiral surface.

Breast Cancer Research and Treatment
Tissue sampling is a problematic issue for inflammatory breast carcinoma, and immediate evaluation following core needle biopsy is needed to evaluate specimen adequacy. We sought to determine if confocal fluorescence microscopy provides sufficient re

In order to diagnose cancer in breast tissue, a sample must be removed, prepared, and examined under a microscope. To provide an alternative to conventional biopsies, an endomicroscope intended to perform optical biopsies is demonstrated. The system

Non-linear microscopy has the potential to provide clinically useful information on the structure of biological tissue in vivo via an endomicroscope. The ability to use plastic as the optical material in a multiphoton objective was evaluated based on

To reduce the number of invasive tissue biopsies and needle aspirations performed during cancer screenings, endo-microscopes can be used to image tissue in vivo. However, when optical fiber bundles are used to transmit the image, the resolution of su

The quality of life of breast cancer survivors is maintained by minimizing adverse effects on their physical appearance. In this study, we present an automated method for computing a common measure of breast symmetry, the normalized Breast Retraction
