Statistical analysis of errors in holographic interferometry
Abstract:
A statistical analysis of the effect of measurement errors on the determination of small vector displacements of diffusely reflecting objects by holographic interferometry is reported. There are two sources of error: inaccurate measurement of fringe-order number and inaccurate measurement of illumination and observation directions. Standard deviations of errors in measured displacements due to these two sources are presented in graphical form for a variety of holographic system geometries. Absolute fringe orders should be measured whenever possible, because fringe readout by scanning leads to very large errors.

Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
