  • Zernike wavefront sensor (ZWFS) development for Low Order Wavefront Sensing (LOWFS) 
    Wang, Xu; Shi, Fang; Wallace, J. Kent (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2016, 2016-06-26)
    ZWFS is known to be photon noise optimal for measuring low order aberrations. Recently, ZWFS was selected as the baseline LOWFS technology on WFIRST for its sensitivity, accuracy, and its ease of integration with the ...
  • Zernike wavefront sensor modeling development for LOWFS on WFIRST-AFTA 
    Wang, Xu; Wallace, J. Kent; Shi, Fang (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2015, 2015-08-09)
    In this paper, we review the theory of ZWFS operation, describe the ZWFS algorithm development, and summarize various numerical sensitivity studies on the sensor performance. In the end, the predicted sensor performance ...
