Photothermal LiDAR for materials characterization

Bibek R. Samanta and Sharvari Zilpelwar

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a highly sensitive range-resolved chemical identification technique using a combination of photothermal spectroscopy and FMCW LiDAR, relying on phase-sensitive detection of the sub-nanometer surface deformations caused due to photothermal absorption.
