摘要： A multispectral harmonisation device intended to align the optical channels of an optronic system that includes at least two directional optical sources emitting respective optical beams of various wavelengths belonging to various spectral bands and comprises a parabolic mirror and means for positioning and orienting each of the optical sources so that each of the optical beams emitted by the optical sources passes through the optical focus of the parabolic mirror before being reflected by said parabolic mirror so that all the optical beams form, by reflection on the parabolic mirror, a multispectral collimated beam.

摘要： A see-through head mounted display with controllable light blocking includes an optics module comprising a light source and image source positioned on a same side of an angled partially-reflective surface, wherein the light source projects light off the surface to the image source which reflects the light as image light to the surface which transmits the image light along a first axis. The display also includes a flat combiner positioned to reflect the image light off of a first side and simultaneously transmit incident light through the first and a second side, along an optical axis perpendicular to the first axis to provide a view of a displayed image overlaid onto a see-through view of the environment, and a controllable light blocking element arranged generally parallel to the flat combiner and in front of the second side to block light incident on the same optical axis as the image light.

摘要： An illumination system configured to provide an illumination beam is provided. At a timing for blue light, first blue light penetrates a light homogenizing element, so that the illumination system outputs blue light of the illumination beam. At a timing for green light, the first blue light is converted into first green light via a phosphor wheel and penetrates the light homogenizing element. At the same time, second blue light is converted into second green light via the phosphor wheel and penetrates the light homogenizing element, so that the illumination system outputs green light of the illumination beam. A projection device is also provided. According to the illumination system and the projection device provided herein, each light source may be effectively utilized.

摘要： An optical device may include a light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The light coupled into the light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

摘要： A beam director for use in 3D printers comprises a first mirror rotating about its longitudinal axis for redirecting a beam onto a second mirror and then onto a work surface, which may result in a beam with a distorted shape. A beam corrector, e.g. a lens or a reflective surface, is used to ensure the beam has the same desired dimensions in the first and second perpendicular direction when striking the work surface.

摘要： A smart mirror can show live or recorded streaming video of an instructor performing a workout in a package that is attractive and unobtrusive enough to hang in a living room. The smart mirror includes a mirror surface with a fully reflecting section and a partially reflecting section. A display behind the partially reflecting section shows the video when the smart mirror is on and is almost invisible when the smart mirror is off. The smart mirror also has a speaker, a microphone, and a camera to enable a user to view the video content and interact with the instructor. The smart mirror may connect to the user's smart phone, a peripheral device (e.g., a Bluetooth speaker) to augment user experience, a biometric sensor to provide biometric data to assess user performance, and/or a network router to connect the smart mirror to a content provider, an instructor, and/or other users.

摘要： A multi channel beamsplitter system operating over a wide spectral band has high optical performance despite the fact that the incoming and/or exiting light is not collimated and its material is dispersive. This is achieved using wavefront compensators that are matched to the curvature of the wavefronts of the incoming and/or exiting light.
