- W2065356720 abstract "It is becoming more common to include HOE's in an optical system. This imposessome important problems for optical designers. In this paper, we will mainly discussanalyses and evaluations of an optical system which contains general HOE's andonly describe briefly the generation of the HOE. A general HOE can be defined asa hologram whose object beam can assume any arbitrary wavefront. The generalapproach, by all known commercial softwares, is to model the required hologram beingformed with simple spherical waves. The wavefront of the object wave is then modifiedby a phase function represented by a high order polynomials. The coefficients are thenoptimize to achieve the required results. This is adequate for most applications. If therequired hologram does not resemble simple spherical waves nor has the symmetry, alarge number of terms may be needed for an accurate representation. Our approachis to use exact ray-tracing to represent a general hologram. This was carried outwith a commercial software, Super-Oslo, which, by the way, has not yet incorporatedthe phase modification feature. Since the Super Oslo can accommodate multipleconfigurations and also since it has the Star Command Language (SCL), we caneither use a separate configuration or dynamically change the main configuration todefine the hologram. The hologram itself is a user defined surface for which you canwrite your own program. Therefore the definition of the hologram can include anyoptical surfaces which can be handled by the software. The hologram can also be onany surface as long as you can write the program for it. The system design, analysisand evaluation can then be run by the SCL. We will use the Holographic Optical Head(HOH) as our example. The HOH includes two spherical lenses and two holograms." @default.
