Inaccurate wavelength calibration for spectral-domain optical coherence tomography (SD-OCT) generates a depth-dependent broadening of coherence peak. In this paper, a simple technique is proposed to eliminate the wavelength calibration error by the s

When a coherent beam transmits through a scattering medium, a random intensity distribution known as speckle is generated. Generally, such speckles can be modulated by feedback-based wavefront shaping, as exemplified by the generation of a bright foc

Measurements of phase refractive indexes of thick objects by using fitting method have been reported in many papers, but the fitting method produces errors in the fitted coefficients of a fitting function. In this paper it is made clear that the thic

A high resolution spectrum analyzer is required to measure a large thickness of a glass plate with a spectral resolved interferometer. In order to solve this requirement, two positions of a reference surface are used to produce short optical differen

To the best of our knowledge, at the present time there is no answer to the fundamental question stated in the title that provides a complete and satisfactory physical description of the structured nature of Hermite-Gauss beams. The purpose of this m

We investigate the optical trapping of polystyrene microspheres in optical tweezers. The transverse capture gradient forces of polystyrene microspheres with different numerical aperture are theoretically and experimentally evaluated by the power spec

A phase refractive index is measured directly from an unwrapped spectral phase distribution whose 2 π ambiguity is determined by fitting the spectral phase distribution with functions based on Cauchy’s equation. The phase refractive index of a qua
