摘要： A video display device includes: a display element displaying images by modulating light from an illumination optical system; and an eyepiece optical system guiding image light from the display element into an optical pupil. The illumination optical system includes: a light source including light emission points arranged substantially linearly; a diffuser plate diffusing illumination light from the light source in a first direction, in which the light emission points are arranged, but not in a second direction perpendicular to the first direction; and an optical element bending the illumination light such that the optical pupil and the light source are substantially conjugate. The optical element includes an illumination mirror, a reflection surface thereof having a non-zero curvature in all sections including a normal line at the optical-axis intersection. Here, the section perpendicular to the first direction has a different curvature from the section perpendicular to the second direction.

摘要： An optical scanning apparatus has a first scanning optical element having a negative power in a sub-scanning direction. A first light beam and a second light beam enter the first scanning optical element through points of an input surface on a same side of a reference surface, which includes an optical axis of the first scanning optical element and being parallel to a main-scanning direction. The second light beam makes a greater angle with the reference surface than the first light beam. A first angle between the reference surface and a principal ray of a first ghost light beam is greater than a second angle between the reference surface and a principal ray of a first normal light beam and is smaller than a third angle between the reference surface and a principal ray of a second normal light beam.

摘要： The invention relates to an objective (4) and to a method for designing said objective (4) for a dental camera (1), the objective (4) comprising at least two lenses (9, 10, 20, 21) and the dental camera (1) comprising a light source (3) and an image sensor (7). An illuminating beam emitted by the light source (3) is focused by the objective (4), imaged on an object (8) to be measured, and reflected by the object (8) to be measured to form a monitoring beam (12). The monitoring beam (12) passes through the objective (4) and is directed toward the image sensor (7), the illuminating beam (11) being partially reflected by surfaces (9′, 9′, 9″, 10′, 10″, 20′, 20″, 21′, 21″) of the lenses (9, 10, 20, 21) to form reflected beams (17.1 to 17.8). The objective (4) comprises means (27) for tilting each lens (9, 10, 20, 21) relatively to the illuminating beam (11) such that the optical axis (9′″ 10′″, 15.1, 15.2) of each lens (9, 10, 20, 21) forms an angle of tilt (α,β) with the illuminating beam (11), the size of said angle being such that the reflected beams (17.1 to 17.8) can be reflected in a direction away from the pupil of the monitoring beam (12).

摘要： A light beam is applied to a front surface of an optical depolarizer. The depolarizer rotates the polarization of light received on different surface positions by different amounts, so that the average incoming polarization is scrambled. The depolarizer has a first and second body that transmit first and second polarization components of the beam with mutually different speeds of light. Each body has two wedge shaped parts of variable thickness, corresponding wedge shaped parts in the two bodies providing light paths of substantially position independent lengths, but with variable rotation of polarization. The wedge shape parts of the front body form a concave input surface for the incoming beam. This prevents cross-over of light between the different wedge shaped parts.

摘要： A rectangular image sensor can be present within an optical capture device. Two lenses can capture and direct light from a real world environment upon the image sensor. Two reflectors can each be positioned between one of the two lenses and the sensor to direct light captured by each lens to produce a corresponding image circle on the sensor. The circles can be produced by the two lenses onto the sensor can be non-overlapping in area. A non-reflective separator can be positioned between the optical pathways of light from the two lenses from the time such light is reflected from the two reflectors respectively. The separator can absorb light from a region surrounding the image circle to prevent optical distortions from the image circles which are in close proximity to each other.
