Rayleigh-sommerfeld diffraction
WebA novel high efficiency image projection system includes a beam-steering modulator, an amplitude modulator, and a controller. In a particular embodiment the controller generates beam-steering drive values from image data and uses the beam-steering drive values to drive the beam-steering modulator. Additionally, the controller utilizes the beam-steering … WebRigorous electromagnetic diffraction theory is employed locally to obtain the field just behind the DL. The field in the focal region is then obtained by use of Rayleigh-Sommerfeld's first diffraction formula, and accurate asymptotic techniques are employed for efficient evaluation of diffraction patterns.
