Abstract
Active Strobe Imager enables us to visualize the dynamic behavior of tissue, even under a high frequent vibration that cannot be followed by the naked eye. A pneumatic actuator imparts a vibration to the target object. By flashing light with a slightly different frequency from the object frequency, we can see the dynamics of object by the naked eye. The vibration we can observe depends on various parameters such as frequency and duty ratio. We formulate the parameter optimization problem by considering the observability of object under strobe condition. By applying the full search method for the problem, we discuss the optimum set of parameters. We also confirmed the effectiveness of the optimized parameters through experiment.
