Background

Many industries and research domains measure functional signals (Ex:  light emission, photo-induced current) using focused laser beams. No technique exists to date to overlay those images with topographical data seamlessly and quantitatively.

Technology Overview

Novel algorithms along with hardware modifications to the microscopic / spectroscopic apparatus allows for the collection and processing of reflected laser signal. The captured signal is used to create a topographical map (C) of the sample. That map is then seamlessly overlaid onto the functional data image (B) to create a composite image (D).

Benefits
  • Fast, efficient screening of materials
  • Simple modification to existing designs
  • Allows for easy to see structure-function relationships
