Seismic exploration requirements are constantly pushing the boundaries of measurement capability: very high temperatures and pressures are directly related to the depth of a survey. Electronic systems for producing surveys are inadequate in many deeper boreholes because the electronics are pushed beyond the limits of their capability. An equivalent passive fibre system offers the promise of improved sensitivity, as well as considerably better tolerance to higher temperatures. However, to develop this system, it is necessary to design a new optical architecture which aligns with the stringent requirements of the borehole system. Specifically, only a small number of fibres are available, and yet several hundred sensors must be connected. Part of this architecture will rely on the ability to access specific fibres contained in an armoured bundle without damaging or touching the other fibres; the delicate process for achieving this is challenging and requires considerable R&D effort. If successful, this project will enable Avalon Sciences to broaden its market share as well as enter new global markets. Furthermore, the expansion of our optical facilities will provide a unique and useful resource for local SMEs, as well as a valuable oppportunity for local schools to observe more of advanced technology and engineering.

地震勘探要求不断突破测量能力的界限：非常高的温度和压力直接关系到测量的深度。用于生产测量的电子系统在许多更深的井眼中是不够的，因为电子设备被推到了它们的能力极限之外。同等的无源光纤系统提供了提高灵敏度的前景，以及对更高温度的更好耐受性。然而，为了开发这种系统，需要设计一种新的光学结构来满足钻孔系统的苛刻要求。具体地说，只有少量的光纤可用，但还必须连接数百个传感器。这种体系结构的一部分将依赖于在不损坏或接触其他纤维的情况下访问铠装束中包含的特定纤维的能力；实现这一目标的精细过程具有挑战性，需要大量的研发工作。如果成功，该项目将使阿瓦隆科学公司能够扩大其市场份额，并进入新的全球市场。此外，光学设施的扩展将为本地中小企业提供独特和有用的资源，并为本地学校提供一个宝贵的机会，让他们观察更多先进的技术和工程。
