Title:
- Customizing Time of Flight Modulation Codes to Resolve Mixed Pixels

Abstract:
We couple custom binary sequences with sparsity based approaches to address the multi-path problem in time of flight imaging. In particular, we utilize maximum length m-sequences that allow us to produce non band-limited correlation functions. Coupled with a tailored sparse deconvolution approach, we are able to resolve the constituent phases and amplitudes of a mixed pixel measurement. Finally, we demonstrate application scenarios, including depth imaging of near-transparent objects.
