Image analysis of modified Hamming aperture: application on confocal microscopy and holography
Hamed, Abdallah; T. Al. Saeed;
Abstract
Digital truncated and obstructed Hamming apertures are used in a confocal laser scanning microscope (CLSM) to improve
the resolution. The resultant point spread function (RPSF) and the coherent transfer function of the defined microscope,
using the modified Hamming apertures, are computed. The mammographic images are used in the CLSM to test
resolution of the investigated apertures. The image is computed from the modulus square of the convolution product of
the RPSF and the complex amplitude of the object. A comparison with the images obtained in case of circular uniform
apertures is investigated. Another application of holography allows the recognition of the modulated Hamming
apertures
