YOUNG`S INTERFERENCE EXPERIMENT: THE LONG AND
... The traditional view of Thomas Young (1773–1829) is that of an underappreciated genius. He was a child prodigy who could read fluently at the age of two and widely read the classics. By the age of 14 he was acquainted with Latin, Greek, French, Italian, Hebrew, Arabic, and Persian. Because of his ma ...

12. CONFOCAL MICROSCOPY • Confocal microscopy can render
... Confocal microscopy can render depth-resolved slices through a 3D object by rejecting much of the out of focus light via a pinhole. The image is reconstructed serially, i.e. point by point, using a single photodetector, rather than in parallel (in bright field, phase contrast, etc.), where a 2D ...

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.
