New paper in Optics & Lasers in Engineering with a self-calibration technique for a LCoS display
A new paper published in Optics & Lasers in Engineering presents an experimental method to calibrate a liquid crystal on silicon (LCoS) display by using split-lens configurations displayed on the device. The split-lens directly generates an interference pattern from which the phase modulation is calculated. Additionally, a micro-lens array is displayed on the LCoS, within the same experimental set-up, to implement a Shack-Hartmann wavefront sensor and retrieve the display surface deformation.
This work is entitled LCoS display phase self-calibration method based on diffractive lens schemes, and has been developed by our collaborators at Universitat Autònoma de Barcelona, with the participation of Ignacio Moreno.
