not available for EP1196717Abstract of corresponding document: WO0102774A condensing and collecting optical system includes a collimating reflector (30) and focusing reflector (40). The collimating reflector (30) includes a portion of a paraboloid of revolution having a focal point (36) and a optical axis (38). The focusing reflector (40) includes a paraboloid of revolution having a focal point (46) and an optical axis (48). A source of the electromagnetic radiation (20) placed at the focal point (36) of the collimating reflector (30) produces a collimated beam of radiation. The focusing reflector (40) is positioned so as to receive the collimated beam and focus it toward a target (60) positioned at the focal point (46) of the focusing reflector (40).read more

Multimode optical connector
Abstract: The disclosure generally relates to individual optical waveguides, sets of optical waveguides such as optical fiber ribbons, and fiber optic connectors useful for connecting individual optical waveguides or multiple optical fibers such as in optical fiber ribbon cables. In particular, the disclosure provides an efficient, compact, and reliable optical fiber connector that exhibits a low insertion loss for use with multimode optical waveguides. The optical connectors incorporate a unitary light coupling unit combining the features of optical fiber alignment, along with redirecting and shaping of the optical beam.

Aerial projection display with dual reflectors
TL;DR: In this paper, a pair of spherical, parabolic, or elliptical reflectors are positioned and oriented relative to one another such that, when the object is placed at one or more predetermined locations, an image of such object is transmitted to the first reflector of said pair, reflected by said first reflectors to the second reflector, and refocused by the second reflecting reflector as an undistorted 3D image.

Collections and condensing optical system using cascaded concave reflectors
TL;DR: In this paper, an electromagnetic radiation collecting and condensing optical system includes a number of cascaded concave reflectors, which radiate light energy onto the reflectors in such a way that the energy from each source is combined by reflectors into a single output which is used to illuminate a target, such as a core optical fiber.
