    Abstract: An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz 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 heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a phase modulator in the path of one laser beam allows the constructive or destructive interference of the signals on the detector as the laser beams are swept in frequency to be adjusted to achieve greater resolution in one or more selected frequency bands.

    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 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 have two distinct low frequency identification tones respectively that are used in conjunction with a stable optical filter element to permit precise determination of the offset frequency of the lasers.
