Abstract
Conoscopic holography is an incoherent holographic technique based on the properties of crystal optics. More precisely, for each point of the object, the interference pattern between the ordinary and the extraordinary rays is presented. The pattern is a Gabor-zone-lens pattern, with a scale parameter that is a function of the distance of the point. The superposition of the Gabor zone lens from each point of the object is the hologram, which contains information on the shape of the object through the scale-parameter dependence of each point is presented. I present a simplified version of the theory of conoscopic holography. The point-spread function and the transfer function of the conoscopic system are presented by using simple arguments, and the conoscopic hologram is defined. The basic schemes for reconstruction, i.e., retrieving, optically or numerically, this three-dimensional information about the object from the recorded hologram, are presented. Finally, the resolution of the system is quantified.
