Other important areas of research include the development of novel optical techniques for nano-optical measurements, diffractive optics, low-coherence interferometry, optical coherence tomography, and near-field microscopy.

Measurement of the spectral coherence of light requires a nonlinear optical interferometer, such as an intensity optical correlator, frequency-resolved optical gating ( FROG ), or Spectral phase interferometry for direct electric-field reconstruction ( SPIDER ).

Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection ( RVI ), eddy-current testing, and low coherence interferometry

OCT bases itself upon low coherence interferometry.

In conventional interferometry with long coherence length ( laser interferometry ), interference of light occurs over a distance of meters.

The principle OCT is white light or low coherence interferometry.

OCT utilizes low coherence interferometry to differentiate tissues within the eye and create a cross section of a living patients ’ retina non-invasively.

Although they have been largely replaced by diode-pumped solid state lasers and laser diodes, they are now used principally for specialized applications such as interferometry and holography due to their long coherence length and Gaussian irradiance profile.

There are many different techniques which are currently being employed, such as laser triangulation ( triangulation sensor ), confocal microscopy ( used for profiling of very small objects ), low coherence interferometry and digital holography.
