Abstract: The present invention provides a head-mount image display apparatus which is maximumly reduced in size so as to arrange eyepiece optical systems in limited spaces such that the eyepiece optical systems do not touch the user's nose. The head-mount image display apparatus comprises LCD for displaying images for left and right eyes, eyepiece optical systems for guiding the images for left and right eyes displayed on the LCD to left and right eyeballs, body of the display apparatus for supporting the LCDs and the eyepiece optical systems for the left and right eyes such that the LCD and the eyepiece optical system for the right eyepiece is arranged at a predetermined distance from the LCD and the eyepiece optical system for the left eye, wherein corners of the eyepiece optical systems, at least which face a user's nose, are each provided with a chamfered portion planed off so as not to touch the user's nose.

Abstract: An optical apparatus including a luminous flux shaping filter for converting a shape of an incident beam without bending an optical path of the incident beam. A light beam emitted from a focusing laser source comprising a semiconductor laser is converted into a parallel light beam by a collimator lens, and then enters the luminous flux shaping filter. The luminous flux shaping filter is positioned on an optical path in the apparatus in the manner that a major axis of an oval light beam from the collimator lens is perpendicular to a longitudinal area in which the transmittance is the highest in the filter. As a result, the luminous flux shaping filter converts the oval light beam into a substantially circular light beam without bending an optical path of the light beam.

Abstract: An electro-optic window is provided which is powered solely by at least one discrete photovoltaic cell within an electro-optic window. The electro-optic window has front and back spaced-apart glass elements sealably bonded together in a spaced-apart relationship and defining a chamber filled with an electro-optic material. The front glass element has a transparent conductive layer on the face of the front glass element confronting the rear glass element and the rear glass element has a transparent conductive layer on the face confronting the front glass element. The seal is generally disposed along the perimeter of three edges of both glass elements and some distance in from the remaining (fourth) edge. The photovoltaic assembly is electrically connected to the two transparent conductive layers and is placed on the outer perimeter along this fourth edge with the photon-absorbing side of all the photovoltaic cells within the photovoltaic assembly facing in one direction ("out" the window).

Abstract: A lenslet array system for imaging an associated object onto a final image plane includes (i) a first assembly including a baffle structure and a first lenslet array having an associated image plane and (ii) a second assembly including a second lenslet array.The first lenslet array accepts a full field of view subtends by the associated object and forms a plurality of image sections of the associated object on an intermediate image plane. The first lenslet array includes a plurality of positive power lenslets, each of the plurality of lenslets having a focal length f.sub.1 and accepting a unique segment of the full field of view subtended by the associated object. These segments of the full field of view together comprise the full field of view, and each of the lenslets forms one image section corresponding to its segment of the full view.

Abstract: A reflection filter is disposed on a solid state laser so as to preferentially reflect TE or TM modes and to suppress oscillation within the resonator of the non-reflected modes. In one embodiment, the filter includes a layer having a plurality of grooves which may be straight and parallel or curved to approximate the mode shape. In another embodiment, the filter includes a polarization sensitive film, without grooves, which either absorbs or transmits the undesired mode. Specifically described is a buried heterostructure semiconductor DFB laser with such a reflection filter formed on at least one facet thereof.
