The Intermediate Optical System of Laser
... Ordinary photographic cameras use a single lens to form an image. This has the property that the magnification varies with the distance of the object from the lens. As a result, in pictures of high buildings taken from ground level, the edges are tilted towards the image’s top center. This phenomeno ...

2. Spectral Stray Light
... measurements (Damm 2007) are illustrated in fig. 3. It can be seen that the spectral stray light can span 60 or more channels. The gap around channel 0 is due to the fact that only the out-of-band channels are shown (Damm 2007). While this method quantifies the stray light over “long ranges”, it is ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
