The Doppler Effect of Absorption Spectral Lines in Moving
... Since in the star/atmosphere system both velocities are the same, (VE = VD), one is tempted to say, from Eq. (3.1), that the classical Doppler Effect is zero, just as in the case of the Relativistic Doppler formula which depends only upon the relative velocity between E and D, namely, VED. But here ...

Optical Materials for LWIR Applications
... LWIR is the lack of available optical materials. An engineer designing a visible system has hundreds of different materials at his/her disposal with high variability in optical, thermal, and mechanical properties. Conversely, there are relatively few materials (approximately 10 materials) available ...

Using a common approach the semiclassical theory of nonlinear spectroscopy which assumes a classical optical field interacting with a quantum matter has had a great success in describing coherent measurements [1, 2, 3, 4, 5, 6, 7, 8]. The signals are written in terms of response functions. The respon ...
