Abstract Optical interferometry-based techniques are ubiquitous in various measurement, imaging, calibration, metrological, and astronomical applications. Repeatability, simplicity, and reliability of measurements have ensured that interferometry in

Mindful of several recent developments in the area of wireless optical data transfer over long and short distances, we present a novel technique to transmit data using an optical carrier. With this technique, the irradiance distribution of a Gaussian

In this paper, we present a scheme to simultaneously measure the thickness and refractive index of parallel plate samples, involving no bulk mechanical motion, by deploying an electronically tunable Twyman–Green interferometer configuration. The ac

In this paper, we present an adaptive Twyman-Green interferometer configuration for measuring the thickness of a transparent sample of a known refractive index or vice versa via an adaptive beam control inside a Twyman-Green interferometer.

In this paper, we attempt to automate, compactify, and forego bulk optical motion in existing ruling-based, double frequency-based, and Twyman-Green interferometer-based interferometric focal length measurement techniques via an addition of an adapti

This paper describes the design of a variable optical power splitter which splits input optical signal power into variable ratios between two output ports. The proposed design is a hybrid scheme which uses a conventional Digital Spatial Light Modulat

The non-line-of-sight (NLOS) imaging problem has attracted a lot of interest in recent years. The objective is to produce images of objects that are hidden around a corner, using the information encoded in the time-of-flight (ToF) of photons that sca

A Phasor field [1-4] - defined as the slow-varying envelope of optical irradiance - has been shown to provide a Huygens-like description and practical reconstructions of non-line-of-sight imaging [5]. We provide results from a series of experiments [

The Phasor field (P-field) integral has been shown to describe non-line-of-sight (NLoS) imaging completely for an incoherent underlying optical carrier due to aperture roughness [1-4]. We present a statistical treatment showing an introduction of a P
