Abstract: A display apparatus includes an optical image projection system, first optical propagation system, and second optical propagation system. The optical image projection system projects image light to infinity. The first optical propagation system propagates the image light projected from the optical image projection system in the x-direction. The first optical propagation system deflects a portion of the image light. The second optical propagation system includes a second input deflector that deflects the image light deflected by the first output deflector. The second optical propagation system propagates the image light deflected by the second input deflector in the y-direction and deflects a portion of the image light. The light beam width in the y-direction of the image light emitted from the optical image projection system and the length in the y-direction of the first light guide are greater than the length in the y-direction of the second input deflector.

Abstract: There is provided a practically useful display method that allows viewers to see in-focus images easily. The method includes the steps of providing a lens array including a plurality of lenses, providing display areas at least one of which corresponds to each of the plurality of lenses, displaying partial images of an original image in the display areas respectively, the partial images being different from one another but partially including a same image portion, forming a bundle of beams by beams respectively emergent from the plurality of lenses equivalently, forming virtual images of the respective partial images displayed in the respective display areas by the respective lenses, and forming a single virtual image by superposing the virtual images of the partial images displayed in the respective corresponding display areas formed by the plurality of lenses.

Abstract: A light radiating unit provided at a distal end portion of an optical fiber includes a first light radiating unit having a predetermined length in a longitudinal direction and capable of radiating therapeutic light having first intensity and a second light radiating unit connected consecutively to the first light radiating unit in the longitudinal direction and configured to radiate therapeutic light having second intensity lower than the first intensity. Consequently, even when a bladder, which is a hollow organ, and a urethra, which is a conduit, are irradiated with the therapeutic light at a time, intensity of the therapeutic light with which surfaces (inner wall surfaces) of respective parts are irradiated is equalized.
