More Book Details

Description of the Book:

The resolution of an in-line hologram recorded with plane waves in the Fraunhofer region of a circular, opaque, particle is evaluated. From the diffraction integral for the reconstructed, real image the intensity distribution about the image is found. Criteria for determining the edge of the image in addition to determining the plane of focus are specified from the data, and the measurement accuracies are found. The inaccuracies are shown to be a result of the inability of the film to record all of the light diffracted by the particle. The reasons for this, film grain noise and its cutoff frequency and dynamic range, are explained and their relative effects compared for the various particle sizes and recording distances
