  • Patent number: 6816647
    Abstract: An industrially hardened terahertz electromagnetic transmitter and receiver module (29) is disclosed. The electromagnetic wave module has an optic (30) which relays an optical pulse from the delivery fiber (32) to the terahertz device. The relay optic (30) allows for a greatly reduced optical spot size as compared to the output of the optical fiber. Thus, the sensitivity of the overall system is enhanced by improving the efficiency of the terahertz device. The relay optic (30) allows the small spot of light to be aligned to the electromagnetic transmitter or receiver with sub-micron precision.

  • Patent number: 5963284
    Abstract: A liquid crystal display includes a patternable diffusing layer therein positioned between the display's substrates. The diffusing (or diffuser) layer includes a host material having a plurality of particles (e.g. substantially transparent spherical balls or spacers) provided therein in order to perform a diffusion function. The refractive index n.sub.p of the particles is different (i.e. .DELTA.n) from the refractive index n.sub.h of the host material by at least about 0.05, and .DELTA.n is preferably from about 0.05-0.15. In certain embodiments, photoimageable color filters, with diffusing particles embedded therein, function as discrete diffusing members across the passive substrate. In other embodiments, a substantially continuous diffusing layer with a transparent host, including spherical balls embedded therein, may be provided across the passive substrate between the substrate and the color filters.
