•Case Study: Laser Vibrometry Helps To Validate Gossamer Space Structures
NASA is pursuing the development of large ultra-lightweight structures commonly referred to as Gossamer space structures. These structures have large areas and small aerial densities, which complicates ground testing significantly as the ground operations interfaces and gravity loading can become cumbersome. Laser vibrometry has proven to be a critical sensing technology for validating the dynamical characteristics of these Gossamer structures, due to its precision, range, and non-contacting (zero-mass loading) nature.
