Systems and methods for inspecting capsules and capsule fill tube assemblies (CTFA) are provided. The 3-D Surface Mapping System (SMS) is used to generate 3-D surface information of each CFTA used in fusion ignition experiments. The CFTA includes a hollow capsule and an attached fill tube. This fragile CFTA's surface is inspected by using an optical microscope to gain volumetric information of particulates and surface defects at a sub-micrometer scale resolution. In order to completely inspect the entire surface of the CFTA the mechanical system requires multiple linear and rotational stages in addition to end effectors to safely hold the CFTA. By combining the optical microscope along with the mechanical system, a three-dimensional replication of the surface is generated providing information on surface feature defects and particulate sizes.
