SUMMARY:Light-Efficient Holographic Illumination for Continuous-Wave Time-
 of-Flight Imaging
DESCRIPTION:Technical Papers\n\nDorian Chan and Matthew O'Toole (Carnegie 
 Mellon University)\n\nTime-of-flight (TOF) cameras have seen widespread ad
 option in recent years across the entire spectrum of commodity devices. Ho
 wever, these devices are fundamentally limited by their dynamic range, str
 uggling with saturation from nearby bright objects and noisy depth from fa
 rther darker objects. In this work, we explore overcoming these limitation
 s in the context of continuous-wave time-of-flight (CWTOF) devices, by usi
 ng a holographic light source capable of redistributing light according to
  arbitrary patterns. In particular, we propose using such a system to move
  light from overexposed to underexposed regions of a scene, such that the 
 entire scene is well exposed. Such a methodology can be easily integrated 
 with existing illumination schemes for TOF. Our proof-of-concept prototype
  is constructed from off-the-shelf optical components, and demonstrated on
  a number of lab scenes.\n\nRegistration Category: Full Access, Enhanced A
