20080218851 | Coded aperture wide field of view array telescope - A sensor assembly including a detector; a first arrangement for enhancing the resolution of the detector; and a second arrangement for increasing the field-of-view of the detector. In a specific implementation, the detector is a focal plane array of detectors, the first arrangement is a Hadamard mask and the second arrangement is a telescope array with a field-bias element operationally coupled thereto. The field bias optical element is implemented with a prism and grating such as a grism. An arrangement is included for actuating the mask to selectively enable a desired level of resolution and another arrangement is included for actuating the field bias element to select a desired field of view. An arrangement for effecting image motion compensation is included along with an imager, an image processor and a data processor. The telescope array may include refractive elements, reflective elements, and/or catadioptric elements. Likewise, the imager may be refractive, reflective and/or catadioptric. | 09-11-2008 |
20080259448 | System and method for telescope guiding utilizing an artificial reference star - A system and method for telescope guiding requires creating an artificial reference star which is locked to the line of sight of the imaging means of a main telescope in the field-of-view (FOV) of a guide scope. A real guide star is selected using the guide scope, such that both artificial and guide stars are within the FOV of the guide scope. Guiding is accomplished by varying the line of sight such that the positional displacement between the guide and artificial stars on the guide star's focal plane is maintained approximately constant. The artificial star is created by generating a point source of light near the main scope's imaging means, directing the light outside the main scope and retroreflecting it at the same direction angle of the beam exiting the aperture into the guide scope, effectively locking the guide scope to the line of sight of the imaging means. | 10-23-2008 |
20110304907 | OPTICAL SIGHT HAVING A COAXIAL ILLUMINATION FUNCTION - An optical sight includes an outer barrel unit, an objective lens unit, an ocular lens unit, a magnification unit, and an illumination unit. The outer barrel unit extends about an axis and has a front end and a rear end. The objective lens unit is mounted to the front end of the outer barrel unit and has a first optical axis. The ocular lens unit is mounted to the rear end of the outer barrel unit. The magnification unit is disposed in and on the outer barrel unit between the objective lens unit and the ocular lens unit, and has a second optical axis. The illumination unit is disposed on the magnification unit, and includes a light source spaced apart from the second optical axis, and a reflective element for projecting emitted light, which is emitted from the light source, onto the objective lens unit. | 12-15-2011 |
20120038981 | SPACE TELESCOPE SYSTEM - A space telescope system includes, but is not limited to, a support platform configured to orbit astronomical object, a plurality of mirrors mounted to the support platform and spaced apart from one another, the plurality of mirrors being configured to reflect a plurality of focused beams, and a focal plane image combiner positioned to intersect the plurality of focused beams and configured to combine the plurality of focused beams to form a composite image. | 02-16-2012 |
20130222900 | OBJECT FINDER MOUNTING APPARATUS, SYSTEMS FOR VIEWING OBJECTS AND METHODS FOR USING SAME - An object-finder-mounting apparatus comprises: a base for mounting the object-finder-mounting apparatus to an optical instrument; an object-finder-holder assembly coupled to the base and comprising one or more object-finder holders for removably holding an object finder; a projection plate moveably coupled to the base and/or the object-finder-holder assembly for movement between first and second positions; and a shadow-casting member. The object-finder-mounting apparatus is convertible between first and second working modes. In the first working mode, the projection plate is moved to the first position which permits use of the object finder held by the object-finder holders to locate objects. In the second working mode, the object finder is removed from the object-finder holders and the projection plate is moved to the second position. In the second working mode, the shadow-casting member casts a shadow onto the projection plate when the optical instrument is directed toward a luminous object. | 08-29-2013 |
20140022632 | OPTICAL SYSTEM WITH OFF-AXIS PACKAGED ILLUMINATOR - A dual-function optical system including a secondary optical path incorporated, off-axis, within a primary optical path of the system and sharing a single aperture and at least some of the optical components with the primary optical path. In one example, an optical system includes an optical telescope including a plurality of mirrors configured to receive and direct first light rays through an entrance aperture of the optical system along a primary optical path, a detector positioned behind the optical telescope in the primary optical path and configured to receive the first light rays from the optical telescope, and an illuminator positioned behind the optical telescope and configured to produce second light rays and to direct the second light rays to the optical telescope, the optical telescope being further configured to transmit the second light rays along a secondary optical path through the entrance aperture of the optical system. | 01-23-2014 |
