摘要： Light projection systems using white light illumination. One embodiment provides a projection system using white light illumination. The projection system includes an illumination assembly configured to receive a white light input. A prism is configured to separate the white light input into color light inputs, redirect the color light inputs to respective modulators, and combine modulated color light inputs from the respective modulators into a white light output. An optical filter is configured to spatially Fourier transform the white light output to generate a filtered white light output. A projection lens assembly is configured to project the filtered white light output.

摘要： A system for projecting dots onto a three-dimensional image is configured to activate multiple pseudo-random dot projectors sequentially. Each pseudo-random dot projector includes an illumination source and a wavefront modulating element (WME) located along an optical axis in a path traversed by radiation produced by the illumination source. The system is configured to form images of dots in the projection plane along the optical axis. The system may also include controlling circuitry configured to perform a sequential projection operation on the plurality of pseudo-random dot projection systems to produce a temporal sequence of images and aggregate and process the temporal sequence of images to produce a high-resolution depth image of the three-dimensional surface.

摘要： Technology is described to uniformly apply doses of radiation to a target material. An irradiation device may comprise an enclosure configured to receive a target material and a source configured to emit primary radiation within the enclosure. The primary radiation may be configured to irradiate at least a first portion of the target material. The irradiation device may further comprise a scattering medium disposed within the enclosure. The scattering medium may be configured to produce secondary radiation through scatter interactions in response to the primary radiation, the secondary radiation configured to irradiate at least a second portion of the target material. A thickness of the scattering medium relative to the primary radiation may have a thickness of at least 3 millimeters.

摘要： A multiplexed light field projector device and a multiplexed light field display to output a light field image is described. The projector has a projector base with a projection optical system configured to output light rays to form a projected image, a collimating optical system configured for collimation of the projected image light rays to form a second projected image, which is directed to a display optical system to produce a light field image. Light field projector devices or alternative projector devices may be used individually or in combination with one or more other projectors which can be arranged to form a multiplexed direct projection light field display. The arrangement of projector devices may have an individual or shared display optical system.

摘要： Numerous embodiments of optical relay systems are disclosed. In one embodiment, a laser-processing apparatus includes an optical relay system configured to correct for beam placement errors by maintaining the optical path length of a beam of laser energy between a first positioner and a scan lens. In another embodiment, the optical relay system may include a first lens, a second lens, and a zoom lens assembly arranged between the first lens and the second lens, wherein the zoom lens assembly includes a first lens group and a second lens group. The zoom lens assembly may be movable relative to the first lens and the second lens (e.g., mounted on a positioner, such as a motion stage). The distance between the lenses of the first lens group and the distance between the lenses of the second lens group may be fixed or variable.

摘要： A fire control system comprises a fixed base and a sight assembly rotatably attached to the fixed base. The sight assembly includes an optical range finder for calculating a distance to a selected target and a camera having a zoom lens assembly and an optical sensor for generating an image signal representative of a target scene including a selected target. The zoom lens assembly includes a zoom controller and zoom lens optical elements, wherein the zoom controller is configured to change a magnification of the zoom lens optical elements responsive to a calculated distance to the selected target. In a further aspect, a method for imaging a target is provided.

摘要： Устройство для представления движущихся изображений содержит источник изображения и прозрачный отражающий экран, при этом источник изображения представляет собой монитор, который расположен на динамической платформе, выполненной с возможностью вертикального и горизонтального перемещения. Монитор выполнен с возможностью вращения вокруг оси, перпендикулярной экрану монитора. Прозрачный отражающий экран может быть установлен под углом, предпочтительно 45°, по отношению к источнику изображения. Проецирование изображения от источника изображения, выполненного в виде монитора, непосредственно на прозрачный отражающий экран позволяет получать сформированное изображение в любой момент времени при перемещении источника изображения вправо - влево и/или вверх - вниз, что позволяет обеспечить возможность динамического изменения перспективы виртуального изображения без потери качества изображения и без необходимости контроля фокусировки источника изображения. Вращение монитора вокруг оси, перпендикулярной его экрану, реализует эффект динамического поворота изображения. Сочетание динамического изменения перспективы изображения и его поворота позволяет реализовывать новый тип визуальных эффектов.

摘要： A projection device for displaying construction plans comprises a projector head having projection optics, a laser module, a first mirror galvanometer redirecting incident light from the laser module toward a second mirror galvanometer that redirects further the incident light toward the projection optics. A memory device stores one or more construction plans. A controller operatively connected to the laser module, the two mirror galvanometers, and the memory device chooses a construction plan to be displayed from the memory device, selectively activates the laser module, and selectively causes the first and second mirror galvanometers to follow a path defined by the chosen construction plan concurrently with the selective activation of the laser module so that the incident light redirected toward the projection optics selectively forms a projection of the construction plan on a construction site.
