APPARATUS AND METHOD FOR GENERATING HOLOGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18325706 titled 'APPARATUS AND METHOD FOR GENERATING HOLOGRAM
Simplified Explanation
The patent application describes an apparatus and method for generating holograms using a complex modulation spatial light modulator (SLM).
- The apparatus measures the intensity and phase of a complex light wavefront output from the SLM.
- It analyzes the measured intensity and phase to determine characteristic information of the complex light wavefront.
- An artificial neural network is used to create distortion correction information based on the characteristic information.
- The distortion correction information is then fed back to the complex modulation SLM to correct any distortion in the complex light wavefront.
Original Abstract Submitted
There is provided an apparatus and method for generating a hologram through measuring intensity and a phase of a complex light wavefront that is output from a complex modulation spatial light modulator (SLM); determining characteristic information of the complex light wavefront by analyzing the measured intensity and phase of the complex light wavefront; creating distortion correction information for correcting distortion of the complex light wavefront from an artificial neural network by inputting the characteristic information to the artificial neural network; and feeding back the distortion correction information to the complex modulation SLM.
