Abstract: A method for display of radar data includes performing a first radar scan to obtain, for at least one object (24), a first range reading, a first azimuth reading, and a first altitude reading. A second radar scan is then performed to obtain, for the at least one object (24), a second range reading, a second azimuth reading, and a second altitude reading. Position and travel direction of the at least one object (24) are computed within a predetermined cylindrical volume (20), according to readings from the first and second radar scans. An icon (34) is assigned to the at least one object (24). A reference point (R) is determined for the predetermined cylindrical volume. The icon (34) is then displayed within the predetermined cylindrical volume (20) in stereoscopic form.

Abstract: A method for applying defect correction and calibration to image data (100) in an imaging system using an area spatial light modulator (146), where a tone correction LUT (148?) is applied to the image data (100) to apply calibration correction before applying defect correction using a defect map (122) with an accompanying gain table (124). The tone correction LUT (148) is then applied to the image data in the image modulation assembly (140).

Abstract: A method for determining an optimum gain response in a spatial frequency correction for a projection system comprises the steps of setting a code value (100) to a first code value; projecting a flat field image at the code value; capturing the flat field image (540) with a camera; creating a defect map (70) of defects in the flat field image; applying the defect map to the flat field image to form a corrected image; setting a gain table (80) to a first gain for the corrected image; applying the gain table to the corrected image; registering the corrected image; filtering the registered image; measuring the filtered image for a standard deviation (570); determining whether all gains for producing an under corrected image (60) and an over corrected image have been exhausted for the code value; if all gains have not been exhausted for the code value, set the gain table to the first gain plus n and go to the step of applying the gain table to the corrected image, if all gains have been exhausted go to determining

Abstract: A method for correcting defects (300) in an imaging system (10) that comprises several steps. Transmitting a digital image (370) to at least one spatial light modulator and capturing the resulting image. Comparing variation in intensity between each image pixel and at least one reference image pixel and deriving a correction factor (305) from the comparison. Determining gain of correction (480) at each code value (460) for each image pixel and applying the correction factor (580) and gain to the digital image (510).

Abstract: An improved method is provided for compensating for pixel site defects of a spatial light modulator (30) in an imaging apparatus (10). An image is formed at a first position and directed to a surface (36). Then, an actuator (40) shifts the spatial light modulator (30) over a shift distance to a second position, which is some integer multiple n of the distance between pixels (72) on the spatial light modulator (30). A second image is formed on the spatial light modulator (30), shifted by the shift distance, and directed to the surface (36). Optionally, dithering is provided with an additional shift of an increment of the distance between pixels (72).

Abstract: An improvement for non-uniformity correction in a printing apparatus (10) wherein an image forming assembly (22) forms an image using a plurality of exposure elements, and the amount of exposure energy at each individual exposure element is capable of being varied. A test print (50) is generated, having a series of test patches or zones with predetermined density levels. A scanner (40) scans the test print (50) to obtain density value readings within each test density zone (52) for each pixel that corresponds to each exposure element. Density value readings are averaged. Then, difference in measurement from this average is used to compute a correction factor for each individual exposure element. An image data manager (12) conditions the input data by this correction factor, then sends the conditioned image data to the image forming assembly (22) for printing.
