Paper Abstract

In recording high-speed processes by means of holographic method time resolution is usually determined by the laser pulse duration. Effective resolution can be an order improved if one knows the shape of the laser pulse as is shown in this paper. The contrast of the image reconstructed is determined by the moment it appears in the phenomenon under study (if the latter is within the boundaries of the registering pulse). The threshold contrast of discovery of an object is due to the part of the total laser pulse energy absorbed by the object. To measure the threshold contrast the stationary optical wedge is recorded on the hologram. The threshold contrast and laser pulse shape being defined it is possible to caculate the threshold time interval.
