A method for building a fast scan system is provided in which a scanner moves the scan sensors faster than scanners of the prior art, even though the total distance that the scan sensors move longer. The scan system includes (a) a scan sensor that measures the scan target by moving around it, and (b) a data processing system that calculates a parameter of the scan target from the collected data. The scan sensor, which has a limited sensing bandwidth, is moved along multiple paths along the target at a scan speed that is faster than the scan speed determined by the scan sensor bandwidth, so as to obtain a clear signal directly from the scan sensor output. The target is then recovered from the scan output using a compressed sampling data recovery data processing method. |
