      Non-planar calibration phantoms for optical coherence tomography

      Optical coherence tomography (OCT) is increasingly used in areas such as ophthalmology and contact lens metrology. However, in such cases, image distortion can occur due to the non-planar nature of the measured sample. Postprocessing algorithms can be implemented to correct this distortion. Here we present an OCT phantom designed to confirm the validity of post-processing algorithms used for measuring curved surfaces. A multi-purpose OCT phantom has been created within a fused silica plano-convex lens using the direct femtosecond laser writing technique. This phantom can be used to calibrate and quantitatively assess the performance (e.g. resolution, sensitivity and distortion) of ...

      Arden Photonics introduces new Optical Coherence Tomography (OCT) Validation Phantom

      Arden Photonics Press Release - Arden Photonics is pleased to introduce the new ALS - OP01 Optical Coherence Tomography (OCT) Validation Phantom. The APL-OP01 OCT phantom is designed to enable OCT users to qualitatively and quantitatively characterize the performance of their instruments. The phantom contains four geometrical patterns inscribed within a small silica substrate to form localized refractive index changes. So this small slide can give a comprehensive assessment of an OCT instrument including spatially varying resolution, sensitivity, distortion and scan linearity. The patterns are laser etched in silica which gives excellent stability so the validation phantom can be used to check ...
