    Abstract: A temple adjustment mechanism includes a male side member joined to one side of a lens frame, and a female side member relatively movable to and from the male side member. A temple is hingedly connected to the female side member. The male and female side members are relatively movable between a retracted position and an extended position. A spring is connected between the male and female side members to hold the two side members in their retracted position. A linkage extends between the male and female side members and is manually operable to move the two side members to their extended position from their retracted position. When the male and female side members are moved to their extended position, the female side member is longitudinally spaced from the male side member so that the overall length of the temple is increased.

    Abstract: A spectacle lens is provided with a lens base material and an antireflection film provided on the lens base material (an inner surface and an outer surface seen from a spectacle wearing person). The lens base material is colored with a dye. The antireflection film (antireflection coating layer) is formed by a vapor deposition method such that it slightly reflects incident light in the same color as that presented by the lens base material and transmits all of the remainder. The same color as referred to herein means that the chromaticity coordinate values are equal to each other.

  • Publication number: 20080284979
    Abstract: An eye measurement system may include a target that moves transverse to an optical path from the target to eye, so as to relax accommodation of the lens of the eye. The target may move transverse to the optical path on a display. The patient may be fogged while the target moves transverse to the optical path, and the target may become smaller such that the patient perceives the target to be moving away from the patient. A pupil camera may measure eye position that can be correlated with the position of the target on the display to determine that the patient has maintained fixation on the moving target. A visible measurement light beam may be pulsed subsequent to and/or during motion of the target that relaxes accommodation of the eye so as to avoid visual interference of the measurement light beam with the target on the display.

  • Publication number: 20080284980
    Abstract: The present invention relates to automatic registration and tracking of the eyes of at least one subject. An optical system, including a lens structure, a mask and an image sensor, receives incoming light from a scene containing the subject and directs at least a portion of this light towards the image sensor, which registers spatially distributed light and thus produces primary data. The mask is adapted to alter a basic optical transfer function of the lens structure and the image sensor into an enhanced optical transfer function, which is substantially less sensitive to variations of an unknown distance between the optical system and the subject than the basic optical transfer function. The processing unit is adapted to receive the primary data and process this data to produce resulting eye-tracking data representing a position estimate of the at least one eye and/or a gaze direction for the at least one eye.

  • Publication number: 20080284981
    Abstract: The present invention is directed to an ophthalmologic measurement method which can depict three-dimensional structures of the interfaces of an eye by short-coherence interferometry based on reference points. For this purpose, the pupil is illuminated at a plurality of points by a short-coherence illumination source. The measurement beam reflected at these points by the interfaces and surfaces of the eye is superimposed with a reference beam. The measurement data which are generated in this way are spectrally split by a diffraction grating, imaged on a two-dimensional detector array and conveyed to a control unit which determines a three-dimensional structure of all intraocular interfaces and surfaces of the eye. In the suggested Fourier domain OCT method, the depiction of three-dimensional structures is preferably carried out by spline surfaces or polygon surfaces.

  • Publication number: 20080284982
    Abstract: Spectral separation filters for channels of a 3D image projection incorporate passbands of primary colors. In at least one of the filters, passbands are present in more than 3 primary colors. A set of two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional primary passbands of the first filter allow for an increased color space in projections through the filters compared to filters only having red, green, and blue primaries. The added flexibility of the increased color space is utilized to more closely match a color space and white point of a projector in which the filters are used.

    Abstract: Abstract: A large format communication display system designed and constructed for viewing from extended distances. In accordance with the present invention, using opto-electronic devices, full motion digital video images are projected from within a partially or totally enclosed conveyance on to wall mounted display screens designed for viewing outside a conveyance, while the conveyance is in motion or parked. The general idea of this invention is to remove the barrier of no video or no motion images from mobile or transit displays. The self-contained or modular aspect of this invention allows complete portability and viewing while in transit or on site.

  • Publication number: 20080284984
    Abstract: A folded projection display system includes a wire-grid polarizer placed immediately behind the system's imaging screen. The display system includes an image projector that projects an image beam containing light of a predetermined linear polarization toward the imaging screen. The wire-grid polarizer reflects the light in the image beam away from the screen. The reflected image beam then encounters a ¼-wavelength achromatic retarder that converts the linear polarization to circular polarization. The image beam next hits a mirror that reflects the light back through the ¼-wavelength achromatic retarder, which converts the circular polarization back to linear polarization, with the polarization director rotated 90 degrees from the original polarization direction. The wire-grid polarizer then allows the light to pass through to the image screen.

  • Publication number: 20080284986
    Abstract: In a back-projection image display device, image light outputted from a projection device is reflected by a reflection mirror held by a base frame and projected onto the back of a screen, to display an image on the screen. An image distortion correcting mechanism includes adjustment mechanisms that deform the reflection mirror, drive units that generate driving force necessary for the deformation of the reflection mirror by the adjustment mechanisms, and a control substrate that supplies power to the drive units. The control substrate supplies power to the drive units in response to a control signal supplied from a remote control unit. This allows pin distortion and barrel distortion, as well as trapezial distortion to be corrected by remote control in the back-projection image display device.
