) without being obstructed by the light source 2, the void of center is prevented. Further, by shortening a distance between focal points of the rotary elliptic mirrors of the reflection mirror 3 forming respective sections (P1-P4), a light source device 1 is miniaturized, and light ...
When light reflects off a surface, the angle of incidence is always equal to the angle of reflection. LAW OF REFLECTION Using the Law of Reflection The angle of incidence and the angle of reflection are always measured from the normal and not from the surface of the object. Why? Because s...

Hunter was faced with trying to add light and the appearance of space to a very small kitchen. “The kitchen was what they called a galley kitchen. To open up the space we put mirrors on the wall between the counters

In this study, we investigate the special curve that is formed by the reflection of the light rays emitted from the point light source on the unit sphere from a spherical curved mirror. Also, spherical caustic curves are defined as the geometrical location of the focusing requests of the refle...
In the early 1990s, there was an explosion of activity in diffractive optical elements (DOEs), to tailor light by interference and diffraction rather than by reflection and refraction, but these were mostly limited to scalar structured light. This has since been superseded by computer-generated hol...
Refraction is where light bends when it moves from one medium to another. Light bounces in a particular way, and it bends in a particular way. Today, we're going to investigate reflection and refraction and try to find out how they work using everyday objects. ...
Using it, we first demonstrate multi-spectral programmable beam steering with FOV~18° and absolute efficiencies exceeding 40%. Then, we reprogram the device to achieve multi-spectral lensing with tunable focal distance and efficiencies ~27%. Our design paves the way towards a new class of SLM...
While it is possible to observe similar effects in atomic ensembles60, 61, this situation is atypical and will not be discussed further here. To reproduce the typical case in atomic ensembles where reflection is negligible, we choose a waveguide spacing of k 0 a = π/2, in which case...
