Nanotechnology
Iatia's QPI provides a digital phase contrast solution to transmission imaging techniques at the nanoscale where few other contrast mechanisms are available due to fabrication difficulties for short wavelength radiations like electrons and x-rays.
Visualization
QPI is a valuable contrast mechanism at the nanoscale where absorption is minimal.

Microscopy phase techniques
QPI makes available, at the nanoscale, phase visualization techniques usually associated with optical microscopy, such as Differential Interference Contrast (DIC), Zernike Phase Contrast and Hoffman Modulation Contrast.

High speed processing
Unlike other phase contrast algorithms used in research applications, QPI is a non-iterative and rapid solution allowing for the capture of live video images with a resolution of up to 640x480 pixels at 15 frames a second.
