A compact single channel interferometer to study vortex beam propagation
Sruthy J. Lathika, A. Vijayakumar, Shanti Bhattacharya
We propose and demonstrate a single channel interferometer that can be used to study how vortex beams propagate. The interferometer consists of a multifunctional diffractive optica…
Fresnel incoherent correlation holography with single camera shot
Vijayakumar Anand, Tomas Katkus, Stefan Lundgaard +4
Fresnel incoherent correlation holography (FINCH) is a self-interference based super-resolution three-dimensional imaging technique. FINCH in inline configuration requires an activ…
Improving Dynamic Range of Speckle Correlation based Optical Lever by spatial multiplexing
Vijayakumar Anand, Shanti Bhattacharya, Joseph Rosen
Speckle correlation based optical levers SC OptLev possess attractive characteristics suitable for sensing small changes in the angular orientations of surfaces. In this study, we…
Implementation of a speckle correlation based optical lever (SC-OptLev) with extended dynamic range
A. Vijayakumar, D. Jayavel, M. Muthaiah +2
A speckle correlation based optical lever (SC-OptLev) is constructed for the measurement of small changes in the angle of orientation of a surface. The dynamic range of SC-OptLev i…
