摘要： Selected embodiments use a relatively small image detector and a scanning mirror to obtain effective performance of a larger image detector. An imager with folded optics captures images of different field positions of a field of view (FOV), and stitches the images together for a larger image of the FOV. The stitched image is processed to identify portions of interest within the larger image, for example, using a cuing algorithm. The portions of interest are scanned again to capture enhanced quality images using, for example, longer dwell time for enhanced contrast. Another image of the FOV or a part of the FOV is stitched together using the enhanced quality images.

摘要： Selected described embodiments include an imager providing concurrent wide field of view (WFOV) and foveated images. The imager includes a frontend optic configured to receive light from a scene. Corrective optics reduces distortions, and transmits the light to a beam splitter. One portion of the light exiting the beam splitter is focused on a WFOV image detector. A second portion of the light falls on a scanning mirror that can be configured to target a selected field position in the field of view. From the scanning mirror, the light passes through a magnifier and is corrected by an adaptive wavefront corrector. The corrector may be configured to correct aberrations corresponding to the particular field of view selected by the scanning mirror. The light from the wavefront corrector is focused on a foveated image detector. The images captured by the image detectors may be stored, processed, and transmitted to other systems.

摘要： The invention relates to a tunable optical add/drop module (TOADM) monolithically integrated on a single planar lightwave circuit (PLC). The present invention overcomes the shortcomings of the prior art by providing virtual pupils at the interface between the channel waveguides and the slab waveguide on the PLC for focusing each wavelength channel, and additional on-chip lenses on the PLC for transforming the focal plane of the spatially dispersive demultiplexer into a substantially flat plane at the edge of the PLC. On-chip lenses are realized as reflective surfaces within slab waveguiding regions having a surface curvature to provide optical power.

摘要： The present invention extends the concept of a standard array waveguide grating (AWG), which focuses each wavelength component launched via an input AWG to a Rowland circle inside a planar lightwave chip (PLC) where discrete waveguides are located, to one which focuses each wavelength component outside of the PLC chip along a straight line. An array of MEMS mirrors or other redirecting elements is positioned at the focus location for independently redirecting each of the wavelength channels back to any number of selected output AWGs formed on the same PLC chip as the input AWG.

摘要： In selected embodiments, improved image restoration is realized using extensions of Wiener filtering combined with multiple image captures acquired after simple, fast reconfigurations of an optical imaging system. These reconfigurations yield unique (distinct) OTF responses for each capture. The optical imaging system may reduce fabrication cost, power consumption, and/or system weight/volume by correcting significant optical aberrations. The system may be configured to perform independent correction of fields within the total field of regard. The system may also be configured to perform independent correction of different spectral bands.

摘要： A scanning optical spectrometer with a detector array is disclosed, in which position of focused spot of light at the input of a dispersive element such as arrayed waveguide grating (AWG) with a slab input, is scanned using a micro-electro-mechanical (MEMS) tiltable micromirror so as to make the dispersed spectrum of light scan over the detector array coupled to the AWG. Sub-spectra recorded using individual detectors are concatenated by a processor unit to obtain the spectrum of input light.
