4. characterization of phase modulation
... A twisted nematic liquid crystal display (TNLCD) is a device that changes the state of polarization of light. In a properly controlled environment, consisting in a set of suitably configured optical elements and the TNLCD, the change in the state of polarization of light can be used to modulate the ...

Surface Waves
... Optical Tamm States (OTSs) can be formed at the interface between two periodic structures. The first has a period close to the wavelength. The second has a period close to the double of the wavelength. • Superstrate and substrate must have overlapping band gaps, but different periods. • OTSs e ...

Vision and Optical Instruments
... For an eye with this typical 2.00 cm lens-to-retina distance, the power of the eye ranges from 50.0 D (for distant totally relaxed vision) to 54.0 D (for close fully accommodated vision), which is an 8% increase. This increase in power for close vision is consistent with the preceding discussion and ...

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.
