CSA has developed capabilities in active and adaptive optics over years of work on technology development for defense and science applications with stringent pointing and beam control requirements. Our experience covers analysis, design, and control using fast steering mirrors and deformable mirrors and advanced sensors. This capability has direct relevance to newer systems for semiconductor manufacturing and telecom applications.

  Example of Integrated Model for Space-Based Laser

  

  Wavefront Fitting Analysis

  Wavefront simulation models actuator dynamics, influence function, sensor dynamics and response, the control algorithm, and input phase and intensity.

  

  Sample Fitting Results

  Curves indicate residual rms wavefront error as fraction of input wavefront rms, for various Deformable Mirror configurations, as a function of optical Zernike functions.
