Gravitational wave signals measured by LISA will be superimposed by noise from various sources. Identifying noise sources and suppressing them is a major goal of scientists and technicians working on LISA technology. A significant potential noise source for the LISA metrology is ‘tilt-to-piston coupling.’ This is the generation of an apparent longitudinal signal resulting from a change in angle between the local and received optical beams, caused by the spacecraft jitter. The primary goal of this activity is to demonstrate that imaging systems are a viable means of supressing tilt-to-piston coupling to 25 µm/rad.
