A bicycle reflector appears brighter to the passenger car driver than to the truck driver at the same distance from the vehicle to the reflector. [1] The light beam and the normal axis of the reflector as shown in Figure 2 form the entrance angle. The entrance angle is a function of the orientation of the reflector to the light source.
The corner reflectors were produced by PerkinElmer and Boxton-Beel Inc. Design and fabrication of the array package was completed by Arthur D. Little Inc. [6] Each reflector is 3.8 cm (1.5 in) in diameter sitting 1.9 cm (0.75 in) below the panel's top surface and mounted between Teflon rings for greater thermal protection. [ 5 ]
The locations of lunar retroreflectors left by Apollo (A) and Luna (L) missions. Retroreflectors are devices which reflect light back to its source. Six were left at six sites on the Moon by three crews of the Apollo program, two by remote landers of the Lunokhod program, and one by the Chandrayaan program. [1]
A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat reflective surfaces. It reflects waves incident from any direction directly towards the source, but translated .
The reflected light is too weak to see with the human eye. Out of a pulse of 3×10 17 photons [25] aimed at the reflector, only about 1–5 are received back on Earth, even under good conditions. [26] They can be identified as originating from the laser because the laser is highly monochromatic.
A modulating retro-reflector (MRR) system combines an optical retro-reflector and an optical modulator to allow optical communications [1] and sometimes other functions such as programmable signage. [2] Free space optical communication technology has emerged in recent years as an attractive alternative to the conventional radio frequency (RF ...
Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses.This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents.
Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface.In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them.
