The use of lasers as a method of sensing allows for a non-invasive form of measurement. Lasers have the ability of deliver a concentrated and pulsed energy of light onto a surface which can then be converted into an ultrasonic wave for detection. This research project will aim to create a remote ultrasonic technique for chemical process monitoring for use in challenging environments. We plan to create a system where light is incident onto a surface, either liquid or gas, is absorbed to create an acoustic wave, and the resultant waves can then be observed to witness real time chemical events.There are many situations to which this application would be useful such as in environmental and biomedical applications where a remote form of measurement is required in corrosive and sterilized environments. The final device will be able to compete commercially against more complex optical based sensing techniques. Applications will include the differentiation of liquids based on volatile compounds or measuring antibody-antigen interactions. The intention is also to create a mechanism that will accomplish this in real time which will allow for remote ultrasonic sensing and observation of events such as binding of proteins, with a versatile and non-destructive technique.The final design will be a laser-based sensing system capable of real-time process monitoring of multiple chemical events happening simultaneously. This will be achieved by dynamically changing the ultrasonic response of the laser-based system.

使用激光作为感测方法允许非侵入性形式的测量。激光器能够将集中的脉冲光能传递到表面上，然后将其转换为超声波进行检测。该研究项目旨在创建一种远程超声波技术，用于在具有挑战性的环境中使用的化学过程监测。我们计划创建一个系统，其中光入射到一个表面上，无论是液体或气体，被吸收，以创建一个声波，所产生的波，然后可以观察到见证真实的时间chemical events.There有许多情况下，这种应用程序将是有用的，如在环境和生物医学应用中的远程形式的测量需要在腐蚀性和消毒环境。最终的设备将能够在商业上与更复杂的基于光学的传感技术竞争。应用将包括基于挥发性化合物的液体区分或测量抗体-抗原相互作用。其目的还在于创造一种机制，能够在真实的时间内实现这一点，从而能够利用多功能和非破坏性技术进行远程超声波传感和观察诸如蛋白质结合等事件，最终设计将是一种基于激光的传感系统，能够对同时发生的多个化学事件进行实时过程监测。这将通过动态改变基于激光的系统的超声响应来实现。
