Dynamic Characterization of Thin Deformable PVDF Mirror
Dynamic Characterization of Thin Deformable PVDF Mirror by Eric M. Trad, published by BiblioScholar on December 4, 2012, presents a detailed methodology for designing and fabricating membrane-like mirror structures. This edition contains 154 pages and is written in English. The book explores the creation of 5-inch diameter mirrors with low areal densities and specific thicknesses, detailing the integration of control patches that function as actuators for the optical structures.
Readers will find an in-depth examination of the testing and analysis of these mirrors, including static deformation measurements and dynamic actuation capabilities. The study highlights the statistical analysis of maximum deformations under applied voltage and characterizes the acquisition system’s performance, including its sample rate for dynamic actuation. The work contributes to the fields of education and teaching, particularly in the context of advanced optical systems and their applications.
Official synopsis Publisher
Methodology for the design and fabrication of 5 inch diameter membrane-like mirror structures is explored, resulting in test articles with areal densities as low as 1.57 kg/m2 and a thickness of 1.5 mm. Each optical structure has 7 control patches etched into the PVDF layer, which can be used as actuators. These test articles are utilized to demonstrate the capabilities of an acquisition system to make measurements of static and dynamic actuation of the mirror surface. Static deformations are analyzed statistically and determined to yield maximum deformations in the actuated regions of -2.1 ??m with a standard deviation of 0.33 ??m when 400 volts are applied. The acquisition system was characterized for dynamic actuation of the surface and found to have a sample rate ranging from 4 to 14 Hz. This rate is found to be dependent upon the desired detail level of the surface description as calculated by the wavefront analysis software.
