Abstract: An integrated circuit includes an array of pixels for capturing and processing successive image frames of a moving scene, the array including at least one row of pixels (inputs); and at least one current value register, in which the current value register is configured to store current pixel values captured from the array (inputs). Also included is at least one set of multiple accumulated value registers, in which each accumulated value register is configured to communicate with the current value register. Furthermore, there is included at least one readout register, in which the readout register is configured to communicate with the set of accumulated value registers. A controller is also included for shifting and summing the rows of pixels and outputting a summed column as a time delayed integrated (TDI) signal.

Abstract: Apparatus and methods for detecting and analyzing spectral polarimetric images are disclosed. Spectral polarimetric images are detected by selecting spectral bands of light within light received from a light source and capturing polarimetric images of the selected spectral bands of light. Spectral polarimetric images are analyzed by converting spectral polarimetric images to Stokes images and selecting two or more of the Stokes images for analysis.

Abstract: An imaging apparatus has input optics for obtaining a multispectral image bearing light and a programmable spectral switching section. The programmable spectral switching section has a first lens for directing light toward a dichroic separator that separates the multispectral image bearing light into a plurality of discrete spectral bands, each directed to an optical switch. Each optical switch is selectively enabled to redirect its corresponding spectral band back through the first lens as switched spectral band light. A light path selector element directs switched spectral band light toward an image forming section that has a sensor lens for directing switched spectral band light toward an image sensor. The image sensor forms image data according switched spectral band light from each optical switch. A control logic processor communicates with optical switches and with the sensor, providing instructions for enablement of optical switches and obtaining sensor data.

Abstract: An automated method for analyzing the photometric calibration and image quality performance characteristics of a high resolution storage phosphor reader. A custom fabricated, lead mask test target is secured to a storage phosphor and exposed using a standard medical x-ray source. A storage phosphor reader, to be calibrated, reads the exposed storage phosphor to produce a digital x-ray image. The digital x-ray image is analyzed by means of a computer algorithm which presents analytic results in text and graphical form to isolate reader problems and to quantify calibration status of the reader.
