Measurement of gradient refractive index profile of crystalline lens of fisheye in vivo using optical coherence tomography
We report the use of optical coherence tomography (OCT) for noninvasive measurement of the refractive index profile of a crystalline lens of a fisheye. The approach exploits the fact that OCT provides a direct...

Imaging growth dynamics of tumour spheroids using optical coherence tomography
Optical coherence tomography (OCT) was used to monitor the dynamics of tumour spheroid formation by the hanging drop method. In contrast to microscopy, the estimates obtained using OCT for the volume of the sp...

Optical trap with spatially varying polarization: application in controlled orientation of birefringent microscopic particle(s)
We report the use of the interference of two orthogonally polarized beams for generation of an optical trap with spatially varying polarization. The spatial variation of polarization in the optical trap has be...
