Chapter 2 – Review of length measuring interferometers

... The field of heterodyne interferometry has been made accessible due to the very narrow linewidths of lasers which allows the observation of beats between two laser frequencies. The technique has resulted in a commercial design of interferometer (Hewlett-Packard 5528A) which can be used for distance ...

In contrast, when light is injected into the outer waveguide (1), the far-field shows it exits the system only from waveguide 1. The NSOM measurement confirms the propagating light is localized in wavegui ...

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.
