Waveguides processing

TABLE 3 Comparison of MCP Processing with Conventional Waveguide Processing... 

For typical fiber array core diameter and refractive index difference between the core and cladding, the waveguiding process is of a multimode nature, and allows an assumption of uniform radial intensity distribution that is, both the level populations A s and the laser intensity / are functions of the propagation length z and time t only. In this regime, the laser intensity 1 is described by an equation of the form... 

In the contact mode, a metal rod acts as a waveguide. When it touches a surface, it is stimulated by the high frequencies, ultrasound, on the opposite side of the surface. This technique is used to locate turbulent flow and or flow restriction in process piping. 

Diallyl Phthalate (DAP, DAIP) Powder Excellent humidity resistance. Withstands temperatures over 400 F. Easily processed. Dimensional stability excellent. May be compression, transfer and injection molded. Low cost. Precision potentiometers, RF connectors, waveguide auxiliaries, attenuators, heating panels, heated battery cases. 

The majority of currently deployed IR sensors operate in the near-IR. Although near-IR sensors suffer from limited selectivity and sensitivity due to the relatively unstructured broadband absorptions in this frequency range, the easy availability of waveguides and other instrumentation give this spectral range a significant advantage over the mid-IR. Main application areas involve substance identification and process control.
