The opportunity to apply the illuminating lens of plate tectonics to previously observed geologic relationships may be the most dramatic change Coleman has experienced during his long career, but it's certainly not the only change.
Thanks to the big flexibility in its design, COCOA is able to reconstruct any optical system made of a combination of the following objects: laser, x-hair laser, incoherent source pinhole, lens, mirror, plate splitter, cube splitter, optical square, rhomboid prism, 2D sensor, 1D sensor, distance-meter, tilt-meter, user-defined.
Thus, instead of unobtrusive miniature cameras, American photographers used large-format cameras requiring slow lenses, large plates, and additional flash light.
These include hydrophobic and hydrophilic acrylic designs, plate lenses, and a dual optic lens.
The design of a GRIN PC plate lens which is attached with a linear phononic plate waveguide is proposed.
Compared to a Fresnel zone plate lens with the same feature size, the photon sieve has super imaging performance.
The results of this study may serve as a basis for developing an active micro plate lens and related devices.
In the micro-fabrication, deep reactive ion etching (Deep-RIE) process with a laboratory-made etcher was utilized to fabricate both the GRIN PC plate lens and the linear phononic waveguide on an 80 μm thick AT-cut quartz plate.
A switchable Fresnel zone plate lens is demonstrated using a polymer-stabilized liquid crystal.
