Abstract:
A projection type image display apparatus includes an adjusting sub-frame image generator and a shift amount adjuster. The adjusting sub-frame image generator generates a primary adjusting sub-frame image having a design in which a first line having a first color and a width of an N pixel (N being a natural number) is displayed on a background image having a second color, and a secondary adjusting sub-frame image having a design in which a second line having a third color and a width of an M pixel set to N=M+α (M being an integer equal to or greater than 1, α being an integer equal to or greater than 0) is displayed on a background image having a fourth color. The shift amount adjuster adjusts the shift amount when the display positions of the primary and secondary adjusting sub-frame images on the projection surface are shifted relatively to each other.

Abstract:
An optical device for guiding radiation from an object scene to a detector contains an alignment device for pivoting a field of view of the detector relative to a predetermined direction, a detector optical unit and an optical articulation for guiding the beam path from the pivoted field of view into the detector optical unit. In order to achieve a compact configuration of the device, the optical articulation has a reversing prism, in which beams running in the optical axis of the articulation are refracted towards a mirror surface of the reversing prism and are reflected by the reflection surface.
Abstract:
A viewing instrument having a variable direction of view is disclosed generally comprising a shaft, a sensor mounted in the distal end of the shaft such that the image plane of the sensor is substantially parallel to the longitudinal axis of the shaft, and a reflecting element that rotates about an axis substantially perpendicular to the longitudinal axis of the shaft. In some embodiments, a negative lens is mounted adjacent the reflecting element, and in certain embodiments, a positive lens is positioned adjacent the image sensor.
Abstract:
A holographic display includes: a light source; at least one beam steerer configured to control a propagation direction of a beam emitted from the light source; an optical element configured to condense a beam passing through the at least one beam steerer; and a spatial light modulator configured to form a three-dimensional (3D) image by modulating a beam passing through the at least one beam steerer.
Abstract:
The object of the present invention is to provide a compact projector of simple construction capable of capable of displaying three-dimensional images. The projector includes at least one light source (11), a polarization separation element (2) that separates light from the light source (11) into two linearly polarized light beams whose polarization axes are orthogonal to each other to emit the two linearly polarized light beams in the same direction, a TIR prism (9) that transmits through the two linearly polarized light beams, a reflective light modulation element (8) that receives the two linearly polarized light beams that have been emitted from the TIR prism (9) to modulate and reflect the two linearly polarized light beams toward the TIR prism (9), a projection lens (10) that enlarges and projects the two linearly polarized light beams that have been modulated by the reflective light modulation element (8) and that have been transmitted through the TIR prism (9), and a rotating prism (6) being rotatably arranged in an optical path between the polarization separation element (2) and the reflective light modulation element (8) to emit the two linearly polarized light beams that have entered from the polarization separation element (2) from different positions depending on the rotation of the rotating prism.
Abstract:
Techniques and structure are disclosed for implementing a spatial walk-off compensation mechanism having an integral tilt function. In some embodiments, the mechanism may comprise a tilt-ball mount having an integrated walk-off compensation medium. In some embodiments, the mechanism may be configured to receive an output beam from a non-linear converter (e.g., optical parametric oscillator or OPO) implementing a non-linear medium comprising a bi-refringent material (e.g., zinc germanium phosphide, or ZnGeP2; cadmium silicon phosphide, or CdSiP2). In some embodiments, the walk-off compensation medium may comprise the same material and/or have the same cut as the non-linear medium. In some embodiments, the mechanism may be manually and/or mechanically adjusted/repositioned to reduce beam walk-off and/or to more precisely direct the beam. In some embodiments, the mechanism may be implemented in mid-infrared (MIR) applications. Numerous configurations and variations will be apparent in light of this disclosure.
Abstract:
An optical system is used in a microscope which is provided to observe a sample or in a light emitting device which applies a beam of light such as a laser beam onto a sample. The optical system can form an oblique path of light so that without shifting the sample or the position of the eyes of the observer (or the position of a light source of the light emitting device), the observer can observe (in the case of the light emitting device, it can apply light onto) not only a vertical top side the sample but also a front, rear, left or right side of the sample, or the position of a portion of the sample to be observed (in the case of the light emitting device, a portion onto which light is applied) can be varied.
Abstract:
A system and apparatus for dynamically distributing light are provided. The apparatus includes a source conduit configured to collect light from a light source and transmit the collected light for emission towards an optical switch. The optical switch is moveable between several discrete resting positions, each corresponding to a different one of a plurality of projector conduits. In each resting position, the optical switch directs light from the source conduit to a corresponding projector conduit. Each projector conduit receives the directed light from the optical switch and transmits the light to a corresponding one of a plurality of projectors. The optical switch is also configured to rest at each of the resting positions for respective portions of a given period of time, to regulate what amount of the light emitted by the source conduit during the period of time is received by each projector conduit.
Abstract:
Provided is an endoscope with a handle, an endoscope shaft connected to the handle, and imaging optics arranged in the endoscope shaft. An object can be located in the direction of view of the imaging optics in front of the endoscope shaft. The endoscope may also include a swivellably housed deflecting element that sets the desired direction of view. The deflecting element can be positioned at the distal end of the endoscope shaft facing away from the handle. An actuating element can be attached to the handle, which is mechanically connected to the deflecting element, and with which the swivel position of the deflecting element can be changed in order to set a desired direction of view.
