Abstract

In this paper we compare two implementations of the holographic technique for recording long, nonlinear, elastic waves of low amplitude in solid polymer waveguides: classical holographic interferometry and digital holography. Both implementations are realized in transmission configuration, with recording in the off-axis schematic. The advantages and disadvantages of these implementations are discussed as applied to the investigation of the evolution of shock waves and strain solitons in transparent solid waveguides.

Highlights

Holographic interferometry began to be actively used in research in various fields of physics for several decades
In this paper we report a comparative analysis of experimental results on monitoring the strain soliton formation from shock waves in a solid waveguide by means of holographic interferometry and digital holography
In this paper we have demonstrated that two major holographic techniques, holographic interferometry and digital holography, in in-transmission configuration allow for the monitoring and analyzing of the evolution of long elastic waves of low amplitude in transparent solid waveguides

Summary

Introduction

Holographic interferometry began to be actively used in research in various fields of physics for several decades. Despite much more frequent use of digital holography, especially in the field of microscopy and biology [27,28,29,30,31], holographic interferometry with traditional recording on holographic plates and films is still in demand in a number of applications [32,33,34,35,36]. Among these applications is the recording of elastic waves of different types in solids, in particular, shock and strain solitary waves (solitons) in solid waveguides. Nonlinear elastic waves can be applied for the investigation of the nonlinearly elastic and viscoelastic properties of materials [38,39,40]
