Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device small enough to be embedded in portable and wearable technologies. By rethinking how spectra are measured and processed, the team has demonstrated a spectrometer costing only around $10, operating at a centimeter scale, and capable of applications ranging from industrial quality control to real-time health care monitoring.

    I guess spectral recognition is cheaper and more accurate than image recognition now.

    There you go, welcome for your new research area or business opportunity.

    All jokes aside, this is super exciting if you are interested in instrumentation for environmental monitoring.

    Unlike conventional spectrometers, which rely on dispersing light or algorithmic reconstruction to recover spectra, the convolutional spectrometer physically performs a convolution operation on the incoming light. This is achieved using a simple cascade of optical components with periodic spectral responses, such as unbalanced Mach–Zehnder interferometers or micro-ring resonators.

    Is this thing a spectrometer or a fucking turbo encabulator?

      I literally went onto the comments to post this exact comment about that exact paragraph. Love to see another enjoyer of side fumble prevention.

      I’ve worked with spectrometers and on spectrometry design before, and that quote from the article is intelligible. It’s also pretentious and poorly explained.

        I’ve never worked with spectrometers but physics and chemistry were some of my strongest subjects, so it made some sense to me - but the sentence was definitely written with the intent to say “look peons, I know big science words you do not, and I can string them into a sentence you’ll question the legibility of”.

    It has a base-plate of prefamulated amulite surmounted by a malleable logarithmic casing, aligned in such a way that the 2 main spurving bearings are in-line with the pentameter fan.

    The writing in the linked article is a little weird, as others have pointed out. However the journal publication is very cool. If this is reproducible, it’ll likely have a noticeable impact over the next 10 years or so. We won’t see $10 spectrometers, but we might see handheld ones in a similar format to the cheap IR cameras.

    Here’s the link for anyone interested.

      If you’re familiar with this kind of stuff, do you think this could lead to cheaper and smaller hyperspectral cameras?

      I was so hyped for this thing …
      Then I got it and well, I wasn’t impressed

      Thought, this could lead to check chemicals on the go. Like checking if drugs are contaminated and things like that.
      But it didn’t even got the basics to work…

      Well, was a lesson learned at least
