Journal ArticleDOI
White light differential interference contrast microscope with a Sagnac interferometer
Sanjib Chatterjee,Y. Pavan Kumar +1 more
TL;DR: A new technique for producing a white light differential interference contrast (DIC) image using a lateral shearing, rotation phase shifting Sagnac interferometer (SI) is proposed and the variable BPD provides an excellent means of improving the contrast of the image.
Journal ArticleDOI
Polarization phase-shifting Fizeau interferometer with a cyclic path optical configuration
Sanjib Chatterjee,Y. Pavan Kumar +1 more
TL;DR: In this article, a cyclic path optical configuration was used to generate coherent, virtual point sources at the back focal plane of a corrected telescope objective for producing a pair of mutually tilted collimated beams with linear orthogonal polarizations in a Fizeau interferometer cavity.
Journal ArticleDOI
External measurement of dihedral right angles with cyclic optical configuration
Sanjib Chatterjee,Y. Pavan Kumar +1 more
TL;DR: Methods for overcoming the restriction of measurement accuracy due to beam aperture limitation and the effects of the positional tilt of the RAC have been discussed and results of validation experiments are presented.
Journal ArticleDOI
Measurement of centering error of a lens with cyclic optical configuration
Sanjib Chatterjee,Y. Pavan Kumar +1 more
TL;DR: In this paper, a new technique for the measurement of centering error (CE) of a lens using a cyclic path optical configuration (CPOC) is presented, where the test lens (TL) is placed in the CPOC, adjusted for zero lateral shear.
Journal ArticleDOI
Measurement of the surface profile of a curved optical surface with rotation phase-shifting lateral shear cyclic path optical configuration.
Sanjib Chatterjee,Y. Pavan Kumar +1 more
TL;DR: In this article, phase shifts between the laterally sheared emergent beam components of a cyclic path optical configuration are introduced by applying a small change in the angle of incidence of the incident beam due to the small angular rotation of the setup.
