The light is characterized by freedoms of multiple parameters, e.g. amplitude, phase, frequency/wavelength, coherence, polarization etc. Full exploitation of these parameters is essential for the development of innovative optical metrology. Optical metrology constitutes one of the most important fields of applied optics as it offers unique capability of non-contact, non-destructive and highly-sensitive measurements for testing and inspection of the sample.

At Applied and Adaptive Optics Laboratory in IIST, we explore innovative techniques for optical sensing with applications in optical metrology devoted to astronomy and remote sensing.
