Applied and Adaptive Optics laboratory in the department of physics, has an advanced research facility in optics that facilitate design, development and innovation optics instrumentation and technology. With dedicated instruments, the research excels in the field of control of various parameters of light such as amplitude, phase, spectrum, polarization and coherence leading to its application in optical imaging, sensing and metrology. Optical aberration sensing using the state of the art devices like Shack-Hartmann wavefront sensors, and their corrections using deformable mirrors find immense application in optical imaging and communication through atmospheric turbulence and scattering media. Supporting theoretical research and modelling using pseudorandom phase plates allows deeper investigation into the field. Optical metrology using interferometry, holography, spectroscopy and polarimetry using a variety of light sources such as femto–second lasers, tunable and fixed wavelength lasers, as well as with low coherent light sources and additional controls using state of the art devices such as spatial light modulators, digital micro-mirror devices(DMD) has elevated the research leading to cutting edge technologies of the future. The lab also takes up many R&D projects of ISRO for providing customized design solutions.
