Abstract
Static non-uniformity effects in a coherent biresonant scanning projector are mitigated through correction factors for pulse events during one frame time. According to an analytical approach, a set of input parameters such as scan angle, micro-electromechanical system (MEMS) obliquity, ridge spacing, etc. are used to optimize color-wise luminance uniformity. According to an optimization approach, pulse correction factors are determined using a custom-defined cost function that attempts to optimize for both luminance and color uniformity.
