Technology Summary




Optical Coherence Tomography/OCT» BIOptoscan OS-113

Introduction

Spectral domain optical coherence tomography (SD-OCT) system is designed for low coherence non-invasive interferometric cross-sectional imaging of biological tissues. It can be used for medical diagnosis, biomedical imaging, and subsurface material inspection. Our modular system design allows users to configure the systems to meet their different or changing reserach needs.

Applications

Tomography imaging:
  • posterior segment of eye
  • anterior segment of eye
  • skin abnormality
  • assess skin burn scars
  • many other tissues or samples
  • multilayer film inspection
  • multilayer film thickness measurement
  • 3D subsurface structural inspection
