<p>ISO/TR 14999-1:2005 gives terms, definitions and fundamental physical and technical relationships for interferometric measurements of optical wavefronts and surface form of optical elements.</p>
<p>It explains, why some principles of the construction and use of interferometers are important due to the wave nature of the wavefronts to be measured.</p>
<p>Since all wavefronts with the exception of very extended plane waves do alter their shape when propagating, ISO/TR 14999-1:2005 also includes some basic information about wave propagation.</p>
<p>In practice, interferometric measurements can be done and are done by use of various configurations; ISO/TR 14999-1:2005 outlines the basic configurations for two-beam interference.</p>
<p>The mathematical formulation of optical waves by the concept of the complex amplitude as well as the basic equations of two-beam interference are established to explain the principles of deriving the phase information out of the measured intensity distribution, either in time or in space.</p>
<p>Both random and systematic errors may affect the results of interferometric measurements and error types to be clearly differentiated are therefore described in ISO/TR 14999-1:2005.</p>
