Assignee: REGENTS OF THE UNIV OF COLORADO, A BODY CORPORATE
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. Apparatus for measuring spatially-resolved material properties of a sample comprising:
an optic that focuses an incident beam of light composed of wavelengths at or below the vacuum ultraviolet onto the sample;
a detector configured to collect light that scatters from the sample and generate scatter data;
a device configured to measure power of the incident beam; and
a processor configured to convert scatter data and measured power of the incident beam into spatially-resolved, complex images of the sample, and determine spatially-resolved material properties of the sample from the spatially-resolved complex images without constraining the complex images based on modelled electromagnetic scattering properties of the sample; and
a mechanism for altering an independent parameter of the incident beam between spatially-resolved complex images.
