In order to correct the geocentric distance's error of TDI (Time Delay and Integration) CCD space camera in calculation of image motion compensation
the data source of the earth's height above sea level USGS DEM (United States Geological Survey Digital Elevation Model) has been introduced to make digital elevation map
the match error of the forward direction (the integral direction of TDI CCD) has been greatly decreased by correcting the geocentric distance error
and eliminate the influence to the relative error of image motion velocity
and correct the error generated by the different heights above sea level. After correcting
which greatly improves the imaging quality of TDI CCD space camera. 2011 IEEE.
a model of image motion calculation of nadir has been introduced
the calculation and analysis of the model shows that: the maximum error of image motion velocity about 1.72% has been decreased to 0.06%
and the influence of the geocentric distance error to the relative error of image motion velocity has been analyzed with the model

Annular subaperture stitching interferometric technology can test large-aperture
and the PV and RMS of residual error of the full aperture phase distribution is 0.027 and 0.0023
high numerical aperture aspheric surfaces with high resolution
the relative error of PV and RMS is -0.53% and -0.31%
respectively. The results conclude that this splicing model and algorithm are accurate and feasible. So it provides another quantitive measurement for test aspheric surfaces especially for large aperture aspheres besides null-compensation.
low cost and high efficiency without auxiliary null optics. In this paper
the basic principle and theory of the stitching method are introduced
the reasonable mathematical model and effective splicing algorithm are established based on simultaneous least-squares method and Zernike polynomial fitting. The translation errors are eliminated from each subaperture through the synthetical optimization stitching mode
it keeps the error from transmitting and accumulating. The numerical simulations have been carried on by this method. As results
the surface map of the full aperture after stitching is consistent to the input surface map
the difference of PV error and RMS error between them is -0.0074 and -0.00052 ( is 632.8nm)
respectively
