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.

    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’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”.
