Abstract
The design of a fast multiframe holographic interferometry system for rapidly evolving transparent objects is described. Essential elements to the configuration are a multipulse laser, an electro‐optic deflector (EOD), and a concave spherical mirror. The hologram, EOD and concave mirror are in a circle whose radius is the same as the spherical mirror. The different frames are superimposed on the same area of the hologram. On reconstruction separation of multiple images is achieved on the Fourier plane of a lens which is used to image the reconstruction of the hologram. The total number of optical components is kept to a minimum and only two of these are used in transmission. Due to the low component count the quality of interferograms obtained is very high.
