A scanned volume computerized tomography scanner in which an electron beam is scanned along a target to generate successive cones of x-rays. A vane collimator receives said x-rays and from successive adjacent fan becomes for irradiating a volume of an object. A detector array receives the x-ray fan becomes and generates signals representative of the transmitted x-ray amplitude across the fan beams. The object and x-ray source are rotated relative to one another to collect data for reconstructing an image of the scanned volume.

A tracking system configured to orient light concentrators to face a light source. The system includes a movable support structure for providing global alignment of the light concentrators with the light source. The system also includes a light concentrator (LC) module that is coupled to the support structure and has an array of light concentrators that are in fixed positions with respect to each other. The system also includes a secondary alignment mechanism having a module joint that movably couples the LC module to the support structure and an actuator assembly. The actuator assembly is configured to selectively move the LC module about two axes relative to a pivot point of the module joint thereby orienting the array of light concentrators.

A light energy conversion (LEC) system includes a fluid circuit having a working fluid flowing therethrough and a plurality of light concentrating (LC) modules for converting light energy into electrical energy and for transforming the light energy into thermal energy. The LC modules including a first LC module coupled in series with a second LC module along the fluid circuit. The working fluid absorbs thermal energy while flowing through the first and second LC modules. At least the first LC module includes a light concentrating optical element that is configured to direct light energy toward a focal region and a receiver held at the focal region. The receiver includes a housing having a chamber that holds an energy conversion member. The energy conversion member transforms light energy received from the optical element into electrical and thermal energy.

摘要:
A light concentrating module for transforming light into at least one of electrical and thermal energy is provided. The light concentrating module may be coupled in flow communication with a fluid conversion module and include a primary optical element that has a reflective surface with a plurality of contoured sections. Each contoured section is shaped to reflect light that impinges the contoured section toward a corresponding focal region. The module may also have a receiver system that includes a plurality of energy conversion members positioned proximate to corresponding focal regions. The receiver system also has a working fluid passage for carrying a working fluid that absorbs the thermal energy. The working fluid can be conveyed away from the receiver system through a mounting post that holds the receiver system. In addition, the module may also generate electricity.
