title: Demonstration of a simple technique for determining the M/# of a holographic substrate by use of a single exposure.
abstract: We propose and demonstrate a simple technique for determining the M/# parameter of a holographic recording material. In this method, divergent object and reference beams are used to produce a spatially varying index modulation. One can analyze the resultant diffraction pattern to find M/# by using only a single grating; existing techniques require many gratings.
