Abstract

Imaging resolution, an important performance parameter of OCT systems, can be evaluated by suitable point spread function (PSF) phantoms. In this paper, we propose an innovative method to prepare PSF phantoms by mixing polystyrene microspheres of standard sizes with transparent polymer - polydimethylsiloxane (PDMS). Detailed procedures as well as specific design are described, and the produced PSF phantoms are employed to verify OCT system resolution performance by analyzing corresponding point spread functions. For comparison, images of the standard-size microspheres are provided by measuring the PSF phantoms with optical microscope.
