Resolution is an important figure of merit for imaging systems. We designed, fabricated and tested an optical phantom consisting of a block of SU-8 with bars etched into its surface. This phantom mimics the simplicity of the 1951 Air Force test chart but can characterize both the axial and lateral resolution of optical coherence tomography systems. The phantom was successfully used to find the axial and lateral resolutions of multiple OCT systems.
