摘要

A general approach for eliminating higher order aliasings is developed by using multiple interlaced samplings. The M-fold interlaced samplings can be used to eliminate aliasing up to the M'th order by solving a set of simultaneous linear equations involving an Mx M Vandermonde matrix, thereby increasing the sampling rate by M times. The concept is demonstrated by considering the case of Fresnel zone sampling and reconstruction.# 1999 Society of Photo-Optical Instrumentation Engineers.
