SUMMARY:Light-Efficient Holographic Illumination for Continuous-Wave Time-
 of-Flight Imaging
DESCRIPTION:Dorian Chan and Matthew O'Toole (Carnegie Mellon University)\n
 \nTime-of-flight (TOF) cameras have seen widespread adoption in recent yea
 rs across the entire spectrum of commodity devices. However, these devices
  are fundamentally limited by their dynamic range, struggling with saturat
 ion from nearby bright objects and noisy depth from farther darker objects
 . In this work, we explore overcoming these limitations in the context of 
 continuous-wave time-of-flight (CWTOF) devices, by using a holographic lig
 ht source capable of redistributing light according to arbitrary patterns.
  In particular, we propose using such a system to move light from overexpo
 sed to underexposed regions of a scene, such that the entire scene is well
  exposed. Such a methodology can be easily integrated with existing illumi
 nation schemes for TOF. Our proof-of-concept prototype is constructed from
  off-the-shelf optical components, and demonstrated on a number of lab sce
 nes.\n\nRegistration Category: Full Access, Enhanced Access, Trade Exhibit
