Abstract: An optical assembly includes a light path and at least one optic to be positioned in the path. A support arrangement supports the optic having a foot arrangement including at least one foot that receives a direct manipulation with the foot slidingly engaged against a support surface to move the optic relative to the light path. Movement of the foot may move the optic along a predetermined path. The foot defines a footprint for engaging the support surface and receives the direct manipulation in a way which changes the footprint on the support surface to move the optic responsive to changes in the footprint. A movement arrangement may selectively bias the foot against the support surface during a movement mode, intended to permit movement of the foot against the support surface, and in a locked mode, intended to lock the foot against the support surface.

Abstract: An apparatus for analyzing, identifying or imaging an target including a source of pulsed signals in the range of frequencies from 100 GHz to over 2 THz focused on or transmitted through the target; and a detector for acquiring spectral information from signals reflected from the target and using a multi-spectral heterodyning process to generate an electrical signal representative of some characteristics of the target. The source of pulse signals and the detector are photoconductive switches activated by a pulsed laser beam from a single mode-locked laser.

Abstract: Attaching an attachment surface of an electrically conductive workpiece to an electrically conductive support surface is described. In one aspect, a biasing force is distributed at least partially around a weld region of the workpiece to urge the attachment surface of the workpiece against the support surface in a way which at least resists welding induced movement of the workpiece relative to the support arrangement. An electrode arrangement, having an electrode tip, contacts the workpiece to provide for substantially compliant movement of the electrode tip against the weld region in directions that are parallel to the support surface. In another aspect, a combined manipulation/welding arrangement is supported for controlled movement with a free end configured for engaging the workpiece to bias the workpiece against the support surface to manipulate the workpiece against the surface and to conduct an electrical current, while holding the workpiece, for welding to the support surface.

Abstract: A sample cell includes an annular support surrounding a sample region. A set of reflectors of the annular support define an optical path that reflects a source beam in a sequence of alternating directions through the sample region at a plurality of different angles such that the source beam exits the set of reflectors after having passed through the sample region a plurality of times. A micro-cell is positionable in the sample region including multi-dimensionally distributed nano-pores. A slidingly adjustable lens forms part of source and detector photomixing packages.
