Wavefront reconstruction techniques have enabled important scientific improvements to corrective imaging in astronomy, optometry, and elsewhere. Here, we describe the design of a wavefront reconstruction-based adaptive optics system designed at Santa Clara University (SCU) in the Department of Physics. Our compact system is based on a modified Shack-Hartmann sensor design and can detect wavefront disturbances on the order of tens of nanometers. The full SCU system includes a 635 nm laser, a collimating lens pair, two mirrors, a microlens array, and a commercial CCD camera. The CCD data is analyzed using a least-squares reconstruction algorithm. Here, we present preliminary wavefront reconstruction results obtained with our setup for wavefront perturbations caused by either lens tilt effects or heat-induced air density fluctuations.
