A system performs continuous full linear scan of a flat media. The system includes, in part, a chuck, and at least first, second and third gantries. The chuck is adapted to support the flat media during the test. The first gantry includes at least one linear array of non-contacting sensors that spans the width of the flat media and is adapted to move across an entire length of the flat media. Each of the second and third gantries includes a probe head that spans the width of the flat media and each is adapted to apply an electrical signal to the flat media. Each probe head is further adapted to move along a direction substantially perpendicular to the surface of the flat media during the times when the first gantry is in motion and while test signals are being continuously applied.

The invention provides an agile imaging satellite linear scan strip pre-generating method based on a point target and a satellite three-axis gesture rapid determining method, relates to the field of spacecraft imaging mission planning, and aims to solve the problems that related linear push scanning strip generating methods do not exist in the area of satellite imaging planning in the prior art, push scanning imaging mode realized by agile satellite can not be considered in target planning caused by ignorance of satellite yaw motor performance in an existing satellite gesture determining method with two-axis gesture calculation, and thereby target planning performance is lowered. Geodetic longitude and latitude of each target point to be observed are converted into plane right angle coordinates through screening point target, calculation is optimized, linear scan strips are obtained, and then new target points corresponding to the target points to be observed are determined through the obtained linear scan strips. Corresponding geodetic coordinates of each new target point are calculated, parameters of satellite three-axis gesture are calculated, and the satellite three-axis gesture is determined. The agile imaging satellite linear scan strip pre-generating method based on the point target and the satellite three-axis gesture rapid determining method are suitable for satellite imaging target planning.
