A support structure for a membrane comprises a plurality of support members and at least one flange, including: (a) a first set of spoke-like support members that extend generally from at least one flange toward a common hub and that have a distal end joined to at least one flange and a proximal end joined to the common hub; and (b) at least one subsequent set of spoke-like support members that are distributed between circumferentially adjacent pairs of spoke-like support members from the prior sets and that extend generally from at least one flange toward the hub, each having a distal end joined to at least one flange and a proximal end connected to the nearest circumferentially adjacent pair of spoke-like support members from the prior sets via a pair of approximately straight anchoring support members which join together and form an angular joint at or near said proximal end, with the vertex of said angular joint pointing generally away from the hub.

High-performance, low-stress support structure with membrane

An improved radiation window comprises a film permeable to radiation disposed on a support structure. The support structure comprises a primary transmissive area comprising a plurality of support members defining a plurality of apertures for radiation to pass through; a flange disposed around the periphery of the primary transmissive area having generally greater mechanical rigidity than the primary transmissive area; and a transition region disposed between, and contiguous with, the primary transmissive area and the flange; the transition region having generally greater mechanical rigidity than the primary transmissive area and generally lesser mechanical rigidity than the flange, thereby providing an intermediate rigidity transition between the dissimilar rigidities of the primary transmissive area and the flange. A radiation detection system comprises a sensor configured to detect radiation, disposed behind such an improved radiation window.

Radiation window with support structure

A diffusive device has an array of discrete facets which may be of a size and pattern similar to a fractal. The facet dimensions can be greater than half the wavelength of incident light such that the facets substantially diffract light. A polarizing wire-grid layer comprised of an array of elongated parallel conductive wires with a period less than half the wavelength of incident light may be disposed between, beneath, or above the facets. The wire-grid polarizes the light by substantially reflecting light having an s-polarization orientation and substantially transmitting a portion of light having a p-polarization orientation.

Nano fractal diffuser

A polarizing device, such as a wire-grid polarizer, includes a substantial mono-layer of a corrosion inhibitor without adversely affecting the optical properties of the polarizing device. The polarizing device can include an optical element and a nano-structure, such as an array of a plurality of spaced-apart, elongated elements disposed on a substrate. The corrosion inhibitor is chemically bonded to surfaces of the elements to form the mono-layer. The mono-layer can have a thickness less than 100 Angstroms. A method of forming the substantial mono-layer can include treating the polarizing device with an amino phosphonate, such as a nitrilotris (methylene) triphosphonic acid.

Corrosion resistant wire-grid polarizer and method of fabrication

A mobile, miniature x-ray source includes a low-power consumption cathode element for mobility, and an anode optic creating a field free region to prolong the life of the cathode element. An electric field is applied to an anode and a cathode that are disposed on opposite sides of an evacuated tube. The anode includes a target material to produce x-rays in response to impact of electrons. The cathode includes a cathode element to produce electrons that are accelerated towards the anode in response to the electric field between the anode and the cathode. The tube can have a length less than approximately 3 inches, and a diameter or width less than approximately 1 inch. The cathode element can include a low-power consumption cathode element with a low power consumption less than approximately 1 watt. The power source can include a battery power source. A field-free region can be positioned at the anode to resist positive ion acceleration back towards the cathode element. An anode tube can be disposed at the anode between the anode and the cathode, and electrically coupled to the anode so that the anode and the anode tube have the same electrical potential, to form the field-free region.
