Abstract

We report progress towards a miniaturized laser illumination module (LIM) for illuminating objects with structured light for 3D imaging purposes. The module, when combined with an off-axis camera and a PC, will image volumes in near-real- time at a range-dependent resolution using 256 X 256 resolution elements. The miniaturized LIM comprises a red laser diode source, a hologram, a spatial light modulator and a projection lens.We present optical and electronic design features of the device in terms of constraints on size and manufacturability. The miniature LIM can be applied to diverse 3D imaging problems to include industrial reverse engineering and inspection and medical diagnostics and prosthetics design.
