Adams, Donald Benjamin (2011-10-21)Coherent optical signal processing systems typically require dynamic, low-loss phase changes of an optical signal. Waveform generation employing phase modulation is an important application area. In particular, laser radar ...
-
Guo, Hong (2009-06-02)Mounting evidence suggests that the normal biomechanical state of arteries may include a nearly equibiaxial intramural stress, and that arteries tend to undergo rapid and dramatic remodeling when perturbed from this normal ...
-
Thompson, Michael Thomas (Texas A&M University, 2006-10-30)A fast measurement technique based on the modulation phase-shift technique is developed to measure the wavelength-dependent magnitude and phase responses of optical devices. The measured phase response is in the form of ...
