Methods and mechanisms for correcting a wavefront error in an optical element are disclosed. A wavefront error that is downstream of an optical element in an optical path is determined. A refractive index prescription that reduces the wavefront error is determined. A beam of energy is directed at a surface of the optical element in accordance with the refractive index prescription to alter the surface to change an index of refraction at multiple locations on the surface.

Optical element surface alteration to correct wavefront error

An optical system and method comprising refracting light with a pair of Risley prisms and employing a line-of-sight control unit to adjust the pair.

Mechanisms for identifying energy received from a scene are provided. A coded aperture in an optical system receives energy from a scene. The coded aperture comprises a plurality of wavelength filter sets arranged in a predetermined pattern. Each wavelength filter set is configured to transmit energy in a corresponding wavelength band of a plurality of different wavelength bands. The coded aperture transmits the energy toward a detector array comprising a plurality of detector elements. The detector array generates sensor data that quantifies energy received by each detector element. The sensor data is processed based on the predetermined pattern to identify spatial locations of energy in each corresponding wavelength band with respect to the scene.

Multispectral imaging via coded aperture

A system including a sensor to receive scattered light from a scene in a thermal infrared spectral region, a Modified Integrated Thermal (MIT) band filter to acquire MIT band data within a thermal detection bandwidth, a sub-band filter to acquire a first sub-band data within a first sub-band bandwidth which is within the thermal detection bandwidth. The sub-band filter is a Reference band filter to capture Reference band data or a Reststrahlen band filter to capture Reststrahlen band data. The system also includes one or more processors configured to perform differencing of the MIT band data and the first sub-band data to compute a second sub-band data. The computed second sub-band data is Reference band data when the sub-band filter is the Reststrahlen band filter or the computed second sub-band data is Reststrahlen band data when the sub-band filter is the Reference band filter. A method and a computer software product are also disclosed.

A method and apparatus for enhancing the resolution of three-dimensional imagery data are disclosed. The method includes registering a frame of the three-dimensional imagery data with a template frame; and temporally averaging the registered frame with the template frame. The apparatus includes a program storage medium encoded with instructions that, when executed by a computing apparatus, performs the method and an apparatus programmed to perform the method.

Method and apparatus for enhancing three-dimensional imagery data

An imaging solution that uses a small, adaptable, real-time, scalable, image-processing (SMARTS IP) chip configured to function like any one of a wide range of specialized FPA imaging devices, and a method for configuring and implementing same is provided. Configuration for a wide range of applications and implementations, including ones with or without IDCA assemblies or other types of dewar/cooler structures, is disclosed. A wide range of output data formats, including all SDI-compatible image data formats, may be accomplished. Frame stacking and variable effective resolution and charge well depth levels may be accomplished in output image data based on on-chip image processing techniques. On-chip image processing algorithms may include XR&#x2122;, DRC, NUC, and other similar or related techniques. Image data output compression through on-chip processing is also disclosed.

The present invention relates to a system and method for determining vehicle attitude and position from image data detected by sensors in a vehicle. The invention uses calculated differences between the locations of selected features in an image plane and the location of corresponding features in a terrain map to determine the attitude of the vehicle carrying the sensors with respect to a ground frame of reference.

An apparatus and method for acquiring image data from a scanned, multi-bank time-delay and integrate (TDI) focal plane array (FPA) detector. Specifically a method and apparatus for warping and combining sequentially-acquired image data of a scene portion from multiple TDI detector banks into a single image having improved image quality, thereby providing improved FPA sensitivity. Also, a method and apparatus for enabling sensitivity and areal rate trade-offs in a multi-bank, scanning TDI FPA based on the number of TDI banks being used for sequential imaging of the same scene portion.

Multi-bank TDI approach for high-sensitivity scanners

An array of two or more tunable electro-optical reflecting elements where the phase response of one or more elements may be adjusted by a variety of approaches including, but not limited to: a liquid crystal superstrate, schottky contact(s), ultra-violet radiation pulses, and illumination of photoconductive substrates. Methods and apparatus for direct and/or adaptive control of phase response via the above approaches are also discussed.

Methods and systems for image processing are provided. A method for processing images of a scene includes receiving image data of a reference and a current frame; generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of N registration points; registering the current frame based on the N motion vectors to produce a registered current frame; and updating the image data of the scene based on the registered current frame. Optionally, registered frames may be oversampled. Techniques for generating the N motion vectors according to roll, zoom, shift and optical flow calculations, updating image data of the scene according to switched and intermediate integration approaches, re-introducing smoothed motion into image data of the scene, re-initializing the process, and processing images of a scene and moving target within the scene are provided.
