If we're to reach another star, chemical propulsion will not get us there in any reasonable time frame. We're going to need a different propulsion technology, and one of the most promising seems to be ...

Abstract: When unpolarized light is reflected from a smooth dielectric surface, it becomes partially polarized. This is due to the orientation of dipoles induced in the reflecting medium and applies ...

As we look around a room, we see most objects because light waves bounce off their surfaces and reach our eyes. However, not all surfaces reflect light in the same way. Figure 1. Light reflected from ...

Considering the near-magical function mirrors perform, their construction is surprisingly simple. Most household mirrors are made of glass with a thin layer of metal backing (usually aluminum), and ...

On Earth, water is so intertwined with life that our search for life on other worlds is essentially a search for water. When scientists find exoplanets around distant stars, a primary consideration is ...

Redbird is a compact, portable, and feature-rich diffuse optical imaging (DOI) and diffuse optical tomography (DOT) toolbox for MATLAB and GNU Octave. It provides a fast, experimentally-validated ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Polarization three-dimensional (3D) imaging technology has received extensive attention in recent years because of its advantages of high accuracy, long detection distance, simplicity, and low cost.

In this study, we focused on diffuse reflectance spectroscopy, a rapid and noninvasive spectroscopy technique that has considerable potential for medical diagnosis. In order to better understand and ...
