Talbot and Talbot-Lau effects are frequently used in lensless imaging applications with light,
ultrasound, x-rays, atoms and molecules–generally in situations where refractive optical …

In present communication, a simple technique for determining the focal length using moiré
deflectometry has been proposed. Necessary mathematical premise expressing the focal …

We demonstrate an automated procedure for the detection of collimation position of an
incoherent beam in Lau interferometry using Fourier fringe analysis technique. The …

A procedure for the measurement of focal length and radius of curvature of a lens using
coherent gradient sensing system and Fourier transform fringe analysis technique has been …

A simple and accurate method for determining the focal length of a lens is presented. There
is no need to know the distance between lens principal planes and can be performed with …

We present the study of the wave motion in the Talbot interferometer with an additional
element such as a lens for all related audiences. Our solutions are in the analytic form. A …

In this paper, a simple and accurate method based on Z-scan and parallel moiré
deflectometry for measuring the focal length of microlenses is reported. A laser beam is …

This paper presents a motion-free technique to characterize the focal length of any spherical
convex or concave lens. The measurement test-bench uses a Gaussian laser beam, an …

We demonstrate an automated procedure for detection of collimation position of an
incoherent beam in Lau interferometry using phase shifting technique. The experimental …

This work proposes a method for dioptric power mapping of progressive lenses through dual
wavelength, low-coherence digital speckle pattern interferometry. Lens characterization …
