Atomfair ESI 859 Electronic Speckle Pattern Interferometry (ESPI) Experiment Setup

Atomfair ESI 859 Electronic Speckle Pattern Interferometry (ESPI) Experiment Setup

Product Overview

Atomfair ESI 859 Electronic Speckle Pattern Interferometry (ESPI) Experiment Setup is mainly designed for teaching in colleges and universities. It adopts advanced testing technology, laser beams directly irradiate the test surface, and a digital camera captures the interference fringes formed by speckle particles on the surface before and after deformation to measure the out-of-plane displacement of objects, helping students deeply understand the principles and measurement methods of ESPI technology.

Instrument Features

  1. Light Source: He-Ne laser with wavelength 632.8nm, power ≥1.5mW, single-mode TEM鈧€鈧€, equipped with fully protected safety high-voltage plug, cavity length 250mm.
  2. Equipped with high-definition digital camera for more intuitive and clear observation of experimental phenomena.
  3. Structure: Simple mechanism, high precision, strong sensitivity, non-contact measurement, no darkroom operation required, real-time display of full-field information and fast data processing, widely applicable to object deformation measurement, non-destructive testing, vibration measurement and other scenarios.
  4. Software: Capable of drawing 3D stereograms of the test surface after force deformation with simple and easy operation.

Main Experimental Contents

  1. Understand the names and functions of each component of the ESPI experiment setup, practice light field arrangement and adjustment technology, and be familiar with the measurement principles.
  2. Observe the out-of-plane displacement fringes generated when the center of the disc is under pressure.
  3. Measure the out-of-plane displacement on the horizontal and vertical center lines of the disc and draw the distribution curve.

Main Configurations

  1. Optical components (lenses, plane mirrors, polarizers, beam splitters; 2D adjustment frame, universal base, 1D base, 2D base, etc.)
  2. GY-11 He-Ne Laser (with power supply)
  3. Camera
  4. Matching image processing software
