Far-field holography is now a well-developed technique that has been applied to a variety of problems. Thus a significant number of systems have been engineered. Nevertheless, there are still several important questions that have needed further study. Progress has been made in optimizing the resolution, particularly as it relates to particle shape and noise. Preliminary results are also reported on the effect of semitransparent and fully transparent objects.
