Ph.D in "Adaptive Optics in Electronic speckle pattern Interferometry and Super-resolution".Synopsis:The goal is to apply the wave-front correction to minimize random phase and intensity modulations inherent in the speckle pattern. The wave-front correction is done through LCD Spatial Light Modulator (SLM). Through appropriate feedback to the LCD SLM, the wavefront control is achieved. This adaptive mechanism in the Digital Speckle Pattern Interferometry (DSPI) system has reduced the speckle noise significantly. Another important problem with DSPI is measurement range of deformations dictated by the speckle dimension. We have developed optical superresolution filters and by applying these filters to the speckle field, the speckle dimension along the axial direction increases more than twice with out filters. We termed it as ‘superspeckle’. With superspeckles when DSPI is performed a larger amount of deformation is measured.

• Design, alignment and development of optical systems including adaptive optics systems. Alignment includes Shack-Hartmann wavefront sensors on-board and obtain the stable configuration when telescope is in motion. • Other responsibilities include inspection of optical components with respect to coatings, dust and opto-mechanical stability. • Interdisciplinary work includes study of effects of turbulence and heated components on the image stability and spot size.• Designing of optical subsystems using Zemax software. Coordination and supervision: The on-board alignment and testing of the systems require careful coordination everyday with other teams like electronics and instrumentation, software and mechanical groups at the observatory (Mauna Kea mountain summit). Supervision is carried out over optical technician and laser engineer.
