Introduction Photonics has a wide array of applications in data communications, imaging, light sensing, and surgery. One such field where the utilization of light is particularly useful is ophthalmology. ...
Cervical Cancer Diagnosis: New Minimally-Invasive Screening
Cervical cancer is a growth of abnormal cells on the surface of the cervix. The largest prevalence of this ailment is the so-called squamous cell carcinoma, that comprises approximately 70% of diagnosed ...
What is Sensory Overload?
For most people, they deal with and respond to situations in a relatively straightforward manner. All that is occurring in one’s environment can be easily recognized and assessed, whether consciously ...
Augmented Reality and the Future
Everyone has seen different depictions of future technology in media and entertainment. One of the recurring themes in “futuristic” worlds is holographic screens individuals can interface with. With ...
Freeform Optics Design and Fabrication
Most are used to seeing lenses with very set radii of curvature. Typical lenses have surfaces that are plano, convex, concave, or any combination of those. Even in the cases of aspherical lenses or ...
