摘要: The invention relates to an imaging system for imaging a surface on an astronomical body, such as the Earth. The imaging system such as a satellite imaging system comprises a telescope comprising at least first and second curved mirrors wherein the second mirror is located downstream of the first mirror, relative to a propagation direction of imaged light, a digital image sensor or a slit aperture arranged at the focal plane of the telescope, and an actuator system arranged for tilting the second mirror or other curved mirror located down-stream of the first curved mirror for scanning the line of sight of the imaging system in a scanning direction (221) on the surface within a field of view (231) of the imaging system.

摘要: A lidar system includes one or more light sources configured to generate a first beam of light and a second beam of light, a scanner configured to scan the first and second beams of light across a field of regard of the lidar system, and a receiver configured to detect the first beam of light and the second beam of light scattered by one or more remote targets. The scanner includes a rotatable polygon mirror that includes multiple reflective surfaces angularly offset from one another along a periphery of the polygon mirror, the reflective surfaces configured to reflect the first and second beams of light to produce a series of scan lines as the polygon mirror rotates. The scanner also includes a pivotable scan mirror configured to (i) reflect the first and second beams of light and (ii) pivot to distribute the scan lines across the field of regard.

摘要: A vein imaging device includes: first and second lasers, a scanner, photo detector, memory, and microprocessor. The first laser emits a beam of light at a first wavelength, and the second laser emits a beam of visible light. The scanner is configured to scan the light from the first and second lasers onto the target in a pattern. The photo detector receives the first wavelength of light after being reflected from the target as a contrasted light/dark image of underlying veins, based on differential amounts of absorption and reflection by blood in the veins and surrounding tissue, and outputs a signal representative of the image. The memory receives and stores a sequential plurality of the contrasted images, and the microprocessor uses the stored plurality of the contrasted images to produce an averaged image with greater resolution, which is projected by the second laser onto the target using visible light.

摘要: A laser processing apparatus includes: a laser oscillator configured to oscillate a laser pulse; a first laser deflection unit configured to deflect the laser pulse emitted from the laser oscillator in a two-dimensional direction; a second laser deflection unit having a slower operation speed and configured to deflect the laser pulse emitted from the first laser deflection unit in a two-dimensional direction on a same plane; a laser oscillation control unit configured to control the laser oscillator; and first and second laser deflection control units respectively configured to control operations of the first and second laser deflection units. The first laser deflection control unit controls the first laser deflection unit to successively irradiate the laser pulse to multiple sites along a predetermined track in each of the processing positions in turn, and to change energy of the laser pulse emitted therefrom in a middle of repeated irradiation.

摘要: A mirror device includes a support portion, a movable portion, and a pair of torsion bars disposed on both sides of the movable portion on a first axis. The movable portion includes a frame-shaped frame connected to the pair of torsion bars and a mirror unit disposed inside the frame. The mirror unit is connected to the frame in each of a pair of connection regions located on both sides of the mirror unit in a direction parallel to a second axis. A region other than the pair of connection regions in a region between the mirror unit and the frame is a space. An outer edge of the mirror unit and an inner edge of the frame are connected to each other so that a curvature in each of the pair of connection regions is continuous when viewed from a direction perpendicular to the first and the second axes.
