Publication number: 20200057380Abstract: Systems and methods are provided that combine an amplitude modulation SLM with a phase modulating SLM in the same optical illumination system. The combination of the amplitude modulation SLM and the phase modulation SLM allows the optical illumination to compensate for the limitations of amplitude modulation SLM by using phase modulating SLM and conversely to compensate for the limitations of phase modulation SLM by using amplitude modulating SLM.Type: ApplicationFiled: October 25, 2019Publication date: February 20, 2020Inventors: Cha-Min Tang, Valentina Emiliani, Peter Pennefather
