Coarse-to-Fine Sparse 3D Reconstruction in THz Light Field Imaging

Abstract: THz light field imaging inherently allows capturing the 3D A1 A2 A3 geometry of a target but at the cost of an increased data volume.Compressive sensing techniques are instrumental in minimizing data acquisition requirements. However, they often rely on computationally expensive sparse reconstruction…

Single-Shot Computational THz 3D Imaging

Abstract: Terahertz (THz) imaging holds promise in a wide range of application fields due to the penetration ability of THz radiation, in combination with a relatively low wavelength, as compared to radar, which facilitates generating sharp images. However, existing THz imaging techniques typically rely…

Migration and Narrative Dynamics

How can narrative theory account for the changing roles of storytelling and storysharing in the public sphere? This chapter proposes a new concept of narrative dynamics, one that generates well-constrained descriptions of specific elements, features, or qualities of narratives, as well as programmatic…

A Revised Light-speed Postulate and the Applicability of the Galilean Velocity Transformation in Relativity Theory

The history of the assumption of the equality of light speeds in free space for observers in different rest frames is reviewed. The classical (Galilean) velocity transformation (GVT) is unable to explain the results of various experiments such as Fresnel-Fizeau light-damping in moving fluids, but this…

Experimental Refutation of Einstein’s Symmetry Principle

A well-known prediction of the Lorentz transformation (LT) of Einstein’s theory of Special Relativity (SR) is that when two observers exchange light signals, they will both measure a red shift (lowering in frequency). An experiment with gamma rays was reported by Hay et al. in 1960 in which an absorber…

History of the Lorentz Transformation and Its Failure To Obey the Law of Causality

The experiments which indicated that the speed of light in free space is the same for all observers regardless of their relative state of motion led Voigt to suggest that the classical (Galilean) velocity transformation (GVT) needed to be amended. His solution introduced the concept of space-time mixing,…

The Many Flaws of the Lorentz Transformation

The Lorentz transformation (LT) is one of the most revered set of relationships in modern physics. Overlooked in this broad assessment are a number of clear inconsistencies in its predictions, however, as will be discussed herein. For example, it makes three predictions which are not consistent with…

Hubble’s Constant: The Clock of the Universe

Hubble’s Constant is an experimental relationship between the speeds and separations of galaxies. It is shown that this information can be combined with the results of differential calculus to obtain an estimate of the value of the outward acceleration of each galaxy. On this basis, it is found that…

The Necessity for Fair Evaluation of Objective Criticism of Physical Theories

There are many ways to prove that Einstein’s Special Theory of Relativity (SR) is not valid. For example, the mixing of space and time coordinates predicted by the Lorentz Transformation (LT) is not consistent with the Law of Causality. Moreover, the combination of the FitzGerald-Lorentz length contraction…

Comparison of the Falling Light Experiment and the Ultracentrifuge Gamma Radiation Study

The discovery of the Mőssbauer effect had a great impact on experimental attempts to study basic open questions in the field of relativity. Pound et al. carried out an experiment to measure the variation of the speed of light with gravitational potential by mounting a gamma ray Mőssbauer emitter on the…

The Failure of Both Einstein’s Space-time Theory and His Equivalence Principle and Their Resolution By the Uniform Scaling…

The Lorentz transformation (LT) makes three predictions which are not consistent with one another: Lorentz-FitzGerald length contraction (FLC), time dilation (TD) and light-speed equality for observers in relative motion to one another. The LT also stands in violation of the Law of Causality because…
