Abstract

A spherical reference field is used to construct a digital holography system
with a demonstrated resolution down to 228 line pairs per mm. The reference
field origin from a GRIN lens placed 1mm from the illuminated object.
This allows the use of a standard sensor to record the hologram with the
required numerical aperture. The image is determined by evaluation of the
Rayleigh-Sommerfeld diffraction integral that relates the object field in the
image plane to the object field in the sensor plane. Experimental results are
given for two charge couple device sensors and one complementary metaloxide-
semiconductor active pixel sensor.
