IMAGE OBSERVING METHOD USING IMAGE FIBER

PURPOSE:To observe a sharp image without any coloring phenomenon by vibrating both end parts of an image fiber in two mutually different directions at mutually different periods synchronously to an amplitude larger than the distance between picture elements.

Summary:PURPOSE:To observe a sharp image without any coloring phenomenon by vibrating both end parts of an image fiber in two mutually different directions at mutually different periods synchronously to an amplitude larger than the distance between picture elements. CONSTITUTION:The image of an object 5 obtained by a photographic lens 6 is formed at the incidence end of the image fiber 8 and the image propagated in the image fiber 8 and obtained at the projection end 14 is projected on an image pickup tube 11 through a projection lens 10, so that the image is observed on a monitor television 12. When a negative high voltage which varies periodically is applied to an electrostrictive element, the incidence end 13 and projection end 14 of the image fiber 8 are vibrated in two directions (x and y directions) crossing the optical axis at right angles. The (x)-directional and (y) directional vibrations of the incidence end 13 and projection end 14 synchronize with each other and have the same amplitude, phase, and frequency. Consequently, the influence of the dead space at the clad part of the image fiber 8 is eliminated and no coloring phenomenon occurs.
