Abstract

We design a holographic system which is lensless and compact. There is a beam expander in conventional holographic setup to produce parallel light and then with a beam splitter to separate the light into two parts. One is used to illuminate the objects and the other one as the reference light. In our system, instead of utilizing beam expander to generalize parallel beam, the laser is directly produced by a fiber, which provides a spherical wave with a center in the out port of fiber. For this reason, our system contains less optical components so that the setup would be more compact. The only needed processing is to eliminate the second-order aberration caused by different distance between two path and the off-axis to a small extent. An experiment of aberration compensation by using principle component analysis is given, and the result shows that the system works well.
