A shadowgraph system with a to-and-fro light-reflecting structure was designed and implemented. The system can reduce overall dimensions and improve visualizing sensitivity. A CCD direct imaging approach was introduced to reduce the system noise and realize full automation. The experimental results show that this system can visualize 1.0×10

variations in density gradient
and can be used to visualize experimental simulated internal waves in the study of ocean internal wave dynamics
and can meet the requirement of internal wave visualization with large wave field scale in limited laboratory space.
