    Abstract: Disclosed herein are methods of detecting organic materials, and more particularly, methods of detecting organic materials using terahertz spectroscopy. The method of detecting organic material using terahertz spectroscopy includes suspending organic material in a medium to form a sample; irradiating the sample with an illumination beam of electromagnetic radiation, the illumination beam having a plurality of frequencies in the range of about 100 GHz to about 2 THz; detecting radiation transmitted through and/or reflected from the sample; and, analyzing the detected radiation to identify the organic material, wherein the medium is selected from the group consisting of agar, guar gum, gellan gum, carrageenan, xantham gum, fibrous sodium pectate, and other agar substitutes.

    Abstract: An apparatus for analyzing, identifying or imaging an target including an integrated dual laser module coupled to a pair of photoconductive switches to produce cw signals in the range of frequencies from 100 GHz to over 2 THz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral homodyne process to generate an electrical signal representative of some characteristics of the target with resolution less than 250 MHz. The photoconductive switches are activated by laser beams from the dual laser module. The lasers in the module are tuned to different frequencies and a phase shifter in the path of one beam allows the beams to have an adjustable phase difference.

    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: 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.
