In one aspect, the present invention provides an apparatus for imaging. At least one source (or ) of composite radiation illuminates a field of view . The radiation includes a set of multiple phase-independent partials that are independently controllable and exhibit distinct physical features. A quasi-optical element is disposed between the field of view and a multi-element receiver . The multi-element receiver is disposed to receive image radiation from the quasi-optical element . Particular ones of the receiver elements transform the image radiation into a set of electrical signals that include information relating to features of the partials.

Systems and methods for millimeter and sub-millimeter wave imaging

A driver circuit can be used to drive a matrix display device, such as a liquid crystal display, that includes a plurality of pixels disposed in rows and columns . A first switch has a current path coupled between a high voltage node (e.g., V ) and a group of pixels . As an example, the group of pixels can be a row or a column . A second switch has a current path coupled between a low voltage node (e.g., ground) the group of pixels . A third switch has a current path coupled between an inductive storage element and the group of pixels. The inductive storage element is coupled to an intermediate voltage node (e.g., V ) with a voltage between the voltage at the high voltage node and the voltage at the low voltage node.

Low power drivers for liquid crystal display technologies

A compact transmissive phase retarder for large and high power laser beam applications is proposed. The laser beam is orthogonally incident on the flat input surface of the optical element and is emergent from the optical component via a second flat output surface. The cross-section of the optical element is characterized by a triangularly or trapezoidally folded surface. The folded surface replaces the inclined surface of bulk equivalent elements. The functionality of the device is provided by a multi-layer interferometric structure deposited on the folded structure.

An incoming beam aperture is positioned adjacent a first surface of the first prism , the first surface extending away from the upper surface of the substrate . The second prism is disposed adjacent to the upper surface of the substrate and is spaced from the first prism by a first distance. The third prism is also disposed adjacent to the upper surface of the substrate . The third prism may be spaced from the second prism by the same first distance. An outgoing beam aperture is positioned adjacent a first surface of the third prism . The substrate has phase changing reflective surfaces and along the upper surface between the first prism and the second prism and between the second prism and the third prism
