  • PIXEL INTENSITY MODULATION USING MODIFYING GAIN VALUES
    Publication number: 20230161152
    Abstract: A visual perception device has a look-up table stored in a laser driver chip. The look-up table includes relational gain data to compensate for brighter areas of a laser pattern wherein pixels are located more closely than areas where the pixels are further apart and to compensate for differences in intensity of individual pixels when the intensities of pixels are altered due to design characteristics of an eye piece.
    Type: Application
    Filed: January 9, 2023
    Publication date: May 25, 2023
    Applicant: Magic Leap, Inc.
