A SINGLE-PIXEL HYPERSPECTRAL IMAGING SYSTEM FOR CANCER MARGIN DETECTION
Title
A SINGLE-PIXEL HYPERSPECTRAL IMAGING SYSTEM FOR CANCER MARGIN DETECTION
Author
Peller, Joseph
Date Created
2018
Subjects--Topical
Optics, Physics
Description
We have developed a hyperspectral imaging (HSI) system based on a single pixel camera design to detect differences in tissue properties based on the optical reflectance and autofluorescence spectra of the tissue. The long-term goal of this project...

Subjects--Topical
Mechanical engineering, Optics
Description
Speckle patterns are complex intensity distributions, which occur when an optically rough surface is illuminated with a coherent light. The speckle phenomenon was known to be troublesome when the laser was first introduced, but later it was discov...

Subjects--Topical
Optics, Engineering, Metaphysics
Description
Deflectometry has been introduced as a viable alternative to interferometric measurement of specular freeform optical surfaces. Deflectometry measurements show high repeatability; however, due to the errors remaining after the calibration and data...

Optics
Description
Index-antiguided (IAG) waveguide is promising for high-power application due to simple step-index structure and the property to introduce higher waveguide loss for higher-order-modes (HOMs). The loss ratio between fundamental mode (FM) and 1st HOM...
