WebIf two optical pulses travel through an optical element with a frequency-independent group delay dispersion D 2, and their center optical frequencies differ by Δ ν, their group delay differs by 2 π D 2 Δ ν. The fundamental unit of group delay dispersion is s 2 (seconds squared), but in practice it is usually specified in units of fs 2 or ps 2. WebSince optical engineering products heavily rely on the surfaces and precision, GD&T is widely used. For this reason, in optical engineering, the key function of the datum surface is …
