Abstract: A balloon illumination system, for illuminating a thin film balloon comprising a pair of thin film panels that are heat sealed together to define a balloon interior, the balloon having a balloon top and a balloon bottom, an apex at the balloon top, a mouth at the balloon bottom, and a flat film valve creating a sleeve having a sleeve width. The balloon illumination system comprises a tube having a tube circumference that is substantially equal to two times the sleeve width, a proximal end and a distal end. A light source is located in the tube midway between the proximal end and distal end. An electrical cable extends proximal through the tube from the light source. The distal end of the tube is inserted into the mouth of the tube and is extended through the sleeve until the distal end reaches the apex. Leakage is prevented by the tight fit between the tube and the sleeve. The light source is positioned in the balloon interior midway between the balloon top and balloon bottom.
Abstract: Apparatus and methods that improve the depth resolution of confocal microscopy images using out-of-focus information from within the focal plane of interest (from the x-y direction) and/or from planes above and below the focal plane of interest (from the z-direction). The interaction of (a) a reflective surface or other light-emanating material and (b) the PSF formed by a confocal microscope results in “out-of-focus” information in, above and below the focal plane; this “out-of-focus” information can be measured. Comparing the measurements in the x-y plane, preferably at a plurality of z-positions, can improve the resolution along each of the x, y, and z-axes, increase the number of the photons used in the system, thus improving the signal to noise ratio, and help correct for aberrations, such as spherical aberrations or other optical aberrations, in the optical system of a microscope.
Abstract: The present invention relates to a compact and high-performance prism optical system having, in order in which light rays pass from the object side, a first transmitting surface (4), a first reflecting surface (5), a second reflecting surface (6), a third reflecting surface (7), and a second transmitting surface (8). When an axial principal ray (1) is projected onto a plane defined by three points at which the axial principal ray (1) impinges on the first transmitting surface (4), the first reflecting surface (5) and the second reflecting surface (6), the projected axial principal ray forms an optical path that bends at two consecutive reflecting surfaces (5, 6) in the same direction with respect to the direction of travel of the rays and bends at the other reflecting surface (7) in a direction different from the direction of bending at the two reflecting surfaces. At least one of the three reflecting surfaces is a rotationally asymmetric surface.
Abstract: A stackable multi-fiber ferrule of the present invention enables relatively tighter stacking between fiber arrays, resulting in increased interconnection density. The present invention achieves tighter stacking by incorporating an inner support member having alignment pin grooves on only one side, thereby permitting the thickness of the support member to be reduced. Thus, the thickness of the inner support member may be thinner than that of conventional support members because the inner support member of the present invention does not have to accommodate opposing alignment pin grooves on both sides thereof. Thus, a multi-fiber stackable ferrule in accordance with the present invention will have alignment pin holes on alternating rows of fibers, that is, on every other interface between adjacent support members. Accordingly, a stackable multi-fiber ferrule in accordance with the present invention is capable of improved interconnection density.
Abstract: The present invention is generally directed to a quick connect optical fiber ferrule connector that can be installed in the field without the use of adhesive or epoxy. The connector includes a ferrule having a receiving end, a terminating end, and a tapered ferrule bore disposed therein. The tapered ferrule bore has a larger diameter toward the receiving end than toward the terminating end. Also included is a barrel having a barrel bore disposed therein. The barrel is arranged and configured to receive the receiving end of the ferrule such that the barrel bore and the tapered ferrule bore are axially aligned. An insert having a receiving end, a support end, and a bore disposed therethrough is positioned such that the receiving end of the insert is disposed within the barrel bore and the support end of the insert is disposed within the tapered ferrule bore. The support end is compressible and the insert is tapered such as to correspond with the tapered ferrule bore.

Abstract: In an image display apparatus, between a reflection-type liquid crystal display panel and a light source for supplying illumination light thereto, a half mirror is disposed at an angle. In addition, in the optical path of the light reflected from the liquid crystal display panel and then reflected from the half mirror, a concave mirror is disposed, and, in the optical path of the light reflected from the concave mirror and then transmitted through the half mirror, a polarizing plate is disposed so that, out of the light reflected from the liquid crystal display panel, only the light that conveys an image is directed to an observer's eye. Alternatively, a polarization separation mirror is disposed in place of the half mirror, and a quarter-wave plate is disposed between the polarization separation mirror and the concave mirror instead of using the polarizing plate.

Abstract: A light diffusing film is produced by preparing a paint by adding a light transmissive diffusing material comprising resin beads to a light transmissive resin, and coating the paint on one or both of the surfaces of transparent film substrate made of TAC, to produce a light diffusing layer. In the light diffusing film, the haze value on the surface of light diffusing layer is three or more, the difference between the haze value along the normal and that along the lines ±60° apart from the normal is four or less, and the surface is practically smooth whose roughness is so adjusted as to give a surface roughness Ra of Ra≦0.2 &mgr;m. Application of such a light diffusing film onto a display panel inhibits scattering reflection which would otherwise cause the display to be whitish, reduces the variation of haze values which vary depending on the viewed angle, and thus improves display quality.
