We present an eight million point structured light illumination scanner design. It has a single patch projection resolution of 12,288 lines along the phase direction. The Basler CMOS video cameras are 2352 by 1726 pixel resolution. The configuration consists of a custom Boulder Nonlinear Systems Spatial Light Modulator for the projection system and dual four mega pixel digital video cameras. The camera field of views are tiled with minimal overlap region and a potential capture rate of 24 frames per second. This report is a status report of a project still under development. We will report on the concept of applying a 1D-square footprint projection chip and give preliminary results of single camera scans. The structured light illumination technique we use is the multi-pattern, multi-frequency phase measuring profilometry technique already published by our group.
