... A. The light is extremely monochromatic with wavelength λ= 632.8 nm B. Consequently, the light has high "temporal coherence", meaning as you travel along the direction of propagation, the components of the electric field continue to oscillate like a sine-wave with a single wavelength, amplitude, and ...

Holography
... The biggest challenge of the on-axis holography is the twin-images: a conjugate image locating right in front of the true image. Instead of sending the reference beam and object beam in line, Leith and Upatnieks proposed separating and sending them at different angles. However, to separate the beam ...

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.
