Close-up of the surface of a lenticular print. Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles.
Prism (styled as PRiSM) is a Canadian rock band formed in Vancouver in 1977. They were originally active from 1977 to 1984 and have been active again from 1987 to present. Their classic line-up consisted of lead singer Ron Tabak, guitarist Lindsay Mitchell, keyboardist John Hall, bassist Allen Harlow and drummer Rocket Nor
Fresnel zone antennas belong to the category of reflector and lens antennas.Unlike traditional reflector and lens antennas, however, the focusing effect in a Fresnel zone antenna is achieved by controlling the phase shifting property of the surface and allows for flat [1] [6] or arbitrary antenna shapes. [4]
Prism rotators use multiple internal reflections to produce beams with rotated polarization. Because they are based on total internal reflection, they are broadband—they work over a broad range of wavelengths. [1] Double Fresnel rhomb A double Fresnel rhomb rotates the linear polarization axis by 90° using four internal reflections. A ...
Bi-telecentric lens with 208 mm diameter front element and a C-mount camera interface. A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity.
All three terms were coined by Augustin-Jean Fresnel, in a memoir read to the French Academy of Sciences on 9 December 1822. [1] [2] Fresnel had first described the case of circular polarization, without yet naming it, in 1821. [3] The phenomenon of polarization arises as a consequence of the fact that light behaves as a two-dimensional ...
Propagation of a ray through a layer. The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films.
Some film is moulded with tiny triangular prisms, making a flexible peel-and-stick miniature prismatic panel. The prisms are joined at the edges into a sheet. A prism sheet is somewhat like a linear Fresnel lens, but each ridge may be identical. Unlike a Fresnel lens, the light is not intended to be focused but used for anidolic lighting.
