  • Patent number: 11675179
    Abstract: Disclosed is a novel assembly and method that enables a user to collimate a focused Cassegrain telescope. The assembly, having a secondary mirror and support baffle, comprising an axle, a bearing, and hub, enables a user to precisely rotate or freely spin a Cassegrain telescope's secondary mirror about its optical axis. Incident to freely spinning the telescope's secondary mirror, the user may peer into the telescope's eyepiece and observe a focused image that may wobble, or remain stable, dependent upon how well the telescope's mirrors are aligned. Further, the assembly's eyepiece, comprising a reticle design, enables the observer to measure the magnitude and direction of image shift incident to the secondary mirror spinning. Lastly, the assembly, comprising a radially marked collimating faceplate, and radially marked collimating knob screws, enables a user to make specific adjustments to the telescope's secondary mirror, compensating for the observed image shift, precisely collimating the telescope.

  • Patent number: 8345337
    Abstract: Disclosed is a polygon mirror device with discontinuous angles of reflections discontinuously to reflect a light beam from a light source with at least one angle. The polygon mirror device with discontinuous angles of reflections comprises a motor connecting with a base to rotate the base around a rotation axis. The base has an axial end surface to form a reference plane. The reference plane is approximately perpendicular to the rotation axis. A plurality of reflectors is positioned on the reference plane circularly around the rotation axis. The reflectors tilt relative to the reference plane with respective angles to form respective included angles. When the base is rotated around the rotation axis, at least one of the reflectors is moved to a reflecting location for receiving the light beam from the light source and reflects the light beam with an angle of reflection to form an image at a specific place.

  • Patent number: 8259378
    Abstract: A scanning apparatus operable in the microwave, mm-wave, sub mm-wave (Terahertz) and infrared ranges comprises a primary drum (10) mounted for rotation about a central axis A of the primary drum being hollow and of rectangular polygonal form to provide a number of sides or facets (12, 14) each adapted to transmit such radiation, from a field of view, which is plane polarized in a first direction at 45° with respect to the rotary axis of the drum and to reflect radiation which is plane polarized in an orthogonal direction. Thus, radiation passing into the drum though whichever said side of the drum is currently facing the field of view and passing towards the diametrically opposite side will be plane polarized with a polarization direction such as to be reflected back by that diametrically opposite side towards the rotary axis of the drum.
