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.
