APL – OP01

The APL-OP01 OCT phantom is a device to qualitatively and quantitatively characterize the performance of an Optical Coherence Tomography (OCT) system, including spatially varying resolution, sensitivity, distortion and scan linearity. The phantom contains four geometrical patterns inscribed within a substrate to form localized refractive index changes.

The 4 test patterns are from left to right:

  • Point Spread Function
  • Sensitivity
  • Lateral resolution
  • Distortion

Each of the 4 patterns has different features but they all contain 8 layers. In each pattern, the first layer is located 100µm below the surface of the substrate and the separation between each subsequent layer is 75µm. So the bottom layer is 625µm from the top surface of the substrate.

Optical Coherence Tomography ( OCT )

Optical Coherence Tomography (OCT) is a non-invasive optical imaging modality that provides real-time, 3D images with micron-level resolution and millimeters of imaging depth. OCT images consist of structural information from a sample based on light backscattered from different layers of material within the sample. The non-invasive nature of OCT makes it well suited for imaging samples such as biological tissue e.g. retinal scanning but its is also used to produce high resolution 3D images of materials.
