Handheld Raman Spectroscopy Powered by AI Deep Learning Technology

An interview with Lynn Chandler from CloudMinds Technology, winners of a 2019 Prism Award in the category of sensors and detectors, conducted at Photonics West 2019.

What are the limitations associated with current handheld Raman spectrometers?

The current limitations with handheld Raman spectrometers today are the performance and capabilities of these devices. These devices are lacking a sophisticated software package that can assist the device in analyzing complex mixtures of substances outside of the lab.

Often when people upgrade to handheld Raman spectrometers, these devices are being used for on-site applications on the manufacturing floor or in the field. Additionally, the individuals using these devices sometimes have no technical background and need help from a central intelligence system to accurately measure, detect and analyze compounds.  

How has AI been incorporated into the CloudMinds XITM?

At CloudMinds we use our cloud-based AI for data analysis and incorporate it into the XITM Raman analysis process. We can train the AI software to virtually store an organization’s library of standard spectra for specific compounds. The data can then be trained so it does not adhere to just one spectrum’s specific conditions, taking into account variables like less power, no noise, and light interference.

With XITM’s AI analysis system we can actually alter the conditions to have this standard spectrum exist for hundreds of different scenarios. Individuals using XITM can then use this AI software to accurately match unknown compounds in just seconds.

What benefits will CloudMind's AI technology bring to Raman spectroscopy?

CloudMind’s AI technology brings advanced data analysis to Raman spectroscopy, making identification and analysis more powerful, sophisticated, and allowing for more variation in terms of real-world applications. Additionally, individuals can use the AI technology included in XITM to simulate many cases and environments which normal Raman spectroscopy software could not.

Why do you think AI has never been incorporated into handheld Raman spectroscopy before?

The capabilities and use of artificial intelligence are still relatively new and are used mostly for patterns, for instance facial recognition. For Raman spectroscopy, it does not seem like AI could be easily incorporated or applied in a handheld Raman spectrometer. However, since CloudMinds is an expert in cloud data AI applications, we can easily and effectively combine the power of artificial intelligence with Raman spectroscopy to deliver a solution that can be used in a variety of applications including defense, pharmacy and food safety. 

How do CloudMinds think this device will open up new application areas of Raman spectroscopy?

The XITM handheld Raman spectrometer uses a smartphone base that is more intuitive and user-friendly than traditional Raman spectrometers. With this foundation, the device is less scientific, and more comfortable for individuals without a scientific background to use. Additionally, the intuitive software interface makes even novice users feel comfortable taking measurements using a handheld Raman spectrometer.

At CloudMinds, we’re continuing to explore the applications of handheld Raman spectroscopy and how we can partner with companies to bring this advanced technology out of the lab and into the field. As we explore these applications, we can put the power of handheld Raman spectroscopy into the hands of consumers as well as scientists to help guide our research and help us adapt the device to uses across many verticals. 

What do you hope to gain from being at Photonics West?

CloudMinds is new to the photonic industry, so we hope to raise awareness of our technologies and their applications in this growing industry. Specifically, we want to introduce our XITM Raman Spectrometer, the cloud-based AI technology powering the device, and its application in the field. We also hope to make valuable connections with potential partners and customers during the event.
