LINEAR-ARRAYED ACOUSTICAL HOLOGRAPHY WITH UNEQUALLY SPACED SAMPLING

This paper gives out the reconstruction of images with by linear-arrayed acoustical holography unequal spaced sampling and theoretically analyeses characteristics of the resulted image.The unequally spaced sampling enhances the main image and makes the high-order image rather blur.Thus it makes the identification of objects easier than that does with equal spaced sampling.Unequally spaced sampling is also useful in other forms of imaging system besides acoustical holography.
