ISAM

ISAM, or Interferometric Synthetic Aperture Microscopy is a type of topographic imaging based primarily on a refinement of the medical imaging technique known as OCT (Optical Coherence Tomography).

It's main claim to fame is the ability to produce three-dimensional images even from blurry, out-of-focus data. Like OCT, it's main use is in medical imaging, using a topographic scanning system to scan a living body to convert a map of the interior into data for manipulation in a virtual reality system.

The main improvement over OCT is one of fidelity. ISAM is a more powerful scanning method, capable of much greater detail in each slice, precisely because it is designed to work with out of focus data and includes adaptive optic processing by default. Thus by design, it can make use of data considered too blurry or indistinct for use from standard OCT scans.
