aperture correction
1.The influence of aperture angle for illumination light on uniformity of the color splitting system is discussed and a color aberration correction by means of wedge coating with. gradient thickness is proposed, thus the color uniformity can be obviously improved.
2.In Synthetic Aperture Radar (SAR) systems, the saturation of Analog-to-Digital Converters (ADC) is an important nonlinear noise which will spoil the image and lower calibration precision. Therefore, it is of great significance for the ADC saturation correction.
3.The papersummarizes the image acquirement method with axial panoramic borehole TV (ATV)device. Besides, this paper puts on researchment on depth correction, magnetic declinationand color cast adjustment,and introduces the technology of seamless stitching method andscanline algorithm which adopted to extract lines of pixels from original video tapes,compass azimuth and depth numeric character identification, attitude (orientation, strike,aperture)calculationinDPBCS.
