A Multi-Functional Three-Dimensional Microscopic System with Structured Illumination and Optical Depth Scanning

Case ID:
UA16-181
Invention:

This technology is a telecentric microscope design that reconciles the resolution vs. depth of field issues associated with microscope systems. The microscope's design maintains constant system magnification while it performs a depth scan with an electrically controlled vari-focal lens.

 

Background:
The classic tradeoff between optical resolution and depth of field in microscopy forces a conventional system to take measurements at different depths and then reconstruct three dimensional data for an extended depth of field (EDOF), a time-consuming process due to the limited speed of mechanical movement and complexity of data extraction.

 

Applications:

  • High-performance freeform optics metrology
  • Biomedical imaging


Advantages:

  • Achieves high resolution and depth of field information
  • Supports multiple imaging modalities
  • Addresses the limitations of conventional microdeflectometry and EDOF


Status: issued U.S. patent #10,725,279
