摘要: In the subject three-axis pointing system, the elevation and tip mirror axes are permanently mounted with their rotation axes orthogonal to each other to eliminate gimbal lock over the hemisphere, to avoid high accelerations as the zenith or nadir pointing directions are approached, and to provide optimal two-axis beam pointing control.

摘要: A multi field of view (FOV) imaging system is disclosed. In one embodiment, a dual FOV imaging system includes a composite lens array including a first lens set positioned to focus a first type of FOV and a second lens set positioned to focus a second type of FOV and a composite focal plane array (FPA) including multiple focal plane arrays (FPAs). Further, the composite FPA is disposed at the first type of FOV and the second type of FOV for producing a seamless mosaic dual FOV image of a target region.

摘要: An apparatus for optical spectrometry utilizes a simplified construction, reducing the number of independent optical elements needed while providing a sizeable dispersed spectrum. The apparatus provides a spectral intensity distribution of an input source wherein individual spectral components in the source can be measured and, in some embodiments, can be manipulated or filtered.

摘要: The present invention provides a method and apparatus for compensating for polarization mode dispersion in an optical transmission system without perturbing the laser source. The present invention compensates for PMD by transferring a sufficient fraction of the light signal in an optical transmission system substantially into a single PSP of the system. As a result, each light pulse in a data stream is not substantially mixed with temporally adjacent light pulses or bit periods.

摘要: Methods and apparatus for rapid, accurate OSNR measurements by directly measuring the spectrally-resolved State of Polarization (SOP) variation across each DWDM channel and using a polarization controller to deterministically extinguish the signal across narrow frequency subbands within each DWDM channel. In-band ASE noise is subsequently measured as a function of frequency across the channel bandwidth.
