高度是航空中最重要的测量指标之一。由于大气压力随着海拔高度的增加而降低，因此静压读数可以指示海拔高度。本文的目的是提出一种新的光纤为基础的系统，采用PSP的提示，首先确定压力和温度，后来用于确定高度。使用PSP来测量压力已经得到了广泛的应用。PSP依赖于氧气的淬灭行为，这可能与压力有关。温度也可以同时测定。在所提出的系统中，光纤用于将照明光传递到PSP，并且还经由全内反射收集任何后续发射。多孔反射层确保PSP发光体被有效地照亮，其随后的发射返回到光纤中。该系统在曼彻斯特环境室进行了演示。
The altitude is one of the most important measurements in aviation. Since atmospheric pressure decreases with increasing altitude, static pressure readings can be indicative of altitude. The purpose of this paper is to present a novel fibre optic based system that incorporates PSP at the tips to first determine pressure and temperature, and later used to determine altitude. The use of PSP to measure pressure is well established and has been employed in a wide range of applications. PSP relies on the quenching behaviour by oxygen, which can be related to pressure. Temperature can also be simultaneously determined. In the presented system, the fibre is used to deliver illumination light to the PSP and also collect any subsequent emissions via total internal reflection. The porous reflective layer ensures that PSP luminophores are effectively illuminated with their subsequent emissions returned back into the fibre. The system was demonstrated in the Manchester environmental chamber.
