A hologram is recorded using an object at ( z o = -1, x o = 1) and a point source at ( z r = -5, x r = 2) as a reference. The film is developed with an overall gamma of 2, reinserted in the position of the film during recording and reconstructed using the same point source as that used to construct the hologram. Using laws of ray tracing of the hologram, find and characterize the location of images. Find the ABCD matrix for the process of holographic construction and reconstruction, knowing that it is after all an imaging process.
