Filed: 1995-06-30
Abstract: PURPOSE: To switch a frame showing a photographing range in accordance with photographing form by arranging a hologram reproducing various images of the frame different in shape each according to light radiated from respective different angles on a convex lens in a finder. CONSTITUTION: In the case of standard photographing, a light source 21 is turned on while light sources 22 and 23 are turned off. When reproducing light 24 is radiated to the hologram 1 stuck to a plano-convex lens 18 at a specified angle, the reproducing light 27 is reflected and diffracted toward a concave lens 20 by a layer in the hologram 1 diffracting the light made incident at the specified angle of the reproducing light 24. The reproducing light goes toward the lens 20 as the image of the frame 15, is reflected by a surface on a lens 18 side, goes toward the lens 18, and further is transmitted through the lens 18, so that a photographer 28 can visually confirm the frame 15 showing the range of the standard photographing.  In the case of panoramic photographing, the photographer 28 can visually confirm the frame 17 showing the range of the panoramic photographing, and further in the case of close-up photographing, he(she) can visually confirm the frame 16 showing the range of close-up photographing.

IPC: G02F1/31
Filed: 1990-06-26
Abstract: PURPOSE:To switch a 1st optical transmission line to a 2nd optical transmission line without any instantaneous break nor bit error by varying the branch ratio of signal light. CONSTITUTION:When a route where the signal light is propagated is switched from the 1st optical fiber 2 to the 2nd optical fiber 5, part of the light signal is branched to the optical fiber 5 by an optical switch 4 to an extent where no bit error occurs. In this state, an optical path length adjuster 7 equalizes the optical path length of the optical fiber 5 to the optical path length of the optical fiber 2 and a polarization controller 8 performs control so that the planes of polarization of both light signals cross each other at right angles. When the optical path is equalized and the planes of polarization cross each other at right angles, the intensity of an electric field applied to the optical switch 4 is so adjusted that the crosstalk of switching becomes maximum, and thus the light signals are switched. Consequently, the optical transmission lines can be switched without the instantaneous break nor bit error of the light signals.
