INDICATION OF PRESSURE OVER TIME INSIDE THE FLUID FLOW USING A PNEUMATIC PHOTONIC CRYSTAL
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2019, Vol 16, Issue 1
Abstract
The purpose of this work is theoretical investigation of optomechanical properties of the gasfilled 1D elastic pneumatic photonic crystal functioning as a sensitive optical indicator of pressure which can unite several scales of pressure magnitude. The indicator includes layered elastic platform including a mounted optopneumatic medium, input-output optical fibers and switching valves, all enclosed into a chamber. At the chosen parameters the device has size near 1 mm and may cover the pressure interval (0, 10) bar with accuracy near 1 μbar for actual pressures existing inside a fluid flow system. The controlled deformation of a system of elastic optical membranes creating the optopneumatic medium was considered by methods of theory of elasticity. The bandgap structure and angle-frequency light reflection diagram of a modified under external pressure pneumatic photonic crystal was investigated in the framework of transfer matrix approach. The miniaturized optical devices considered may offer an opportunity to organize simultaneous and total scanning monitoring of fluid pressure in different parts of a technical or biological system.
