Conventional methods of measuring the various parameters of holographic optical elements are tedious for mass production. A novel approach is described for the holographic elements used in the holographic sight, in which the parameters are defined and measured as per their intended final application. Since the holographic sight is used for accurate target acquisition along with the other features, parallax in the sight becomes a critical parameter. Besides, the maximum brightness of the reticle is another parameter of the device, which is important for the use of sight in the strong sunlight in summers. There are two holographic elements, namely holographic reticle and holographic lens in the sight. Both can be tested in a simple set-up in terms of the parallax of the sight and the brightness of the reticle. The masters for both elements are required to be benchmarked once and rest of the elements in a mass production can be tested with the reference of masters.
