A holographic technique has been pioneered that harnesses scattering in interstellar space to resolve the emission from pulsars at a resolution of 50 pico-arcseconds, six orders of magnitude finer than has been achieved by conventional radio astronomical interferometry. This project will directly measure the size of the emission regions in a set of pulsars, and hence resolve the 40-year old debate regarding the site of their radio emission. The project will also apply the technique to binary pulsar systems to provide a new test of General Relativity.

一种全息照相技术已经被开创出来，它利用星际空间中的散射来分辨出50皮弧秒分辨率的恒星辐射，比传统的射电天文学干涉测量法精确6个数量级。该项目将直接测量一组雷达中发射区域的大小，从而解决40年来关于其无线电发射地点的争论。该项目还将把这项技术应用于脉冲双星系统，为广义相对论提供新的检验。
