-high spectral resolution
-arbitrary #RF pulse programming
-requires #LabVIEW
-cost: k$ 20 (mainly PXI waveform generator & digitizer alone)
-cost could be driven down by half using a home-built RF amplifier made with high-power operational amplifiers

The ALEXs 2k512 BI UV X-ray CCD camera captured high-resolution, spatially resolved spectra of soft #X-ray emissions in a recent experiment. Paired with a #spectrometer, the camera provided valuable insights into #photon flux and emission characteristics, helping researchers optimize X-ray generation systems.

[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! https://sky.esa.int/esasky/?hide_welcome=true&hide_banner_info=true&hips=DES-DR2+ColorIRG&sci=false&layout=esasky&euclid_image=EDFS

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

[Focus on the #EnVision mission] Why have #Venus and Earth evolved so differently? This is the question to be answered by the EnVision #SpaceMission of the European Space Agency - ESA, scheduled for launch in 2031.

To this end, the European #probe will carry several instruments - including an imaging #spectrometer, to which IRAP staff are contributing. Observations will be made in the UV and IR domains, in order to monitor temporal variations in #surface temperature and gas concentrations within the #atmosphere - and thus gain a better understanding of interactions between the Venusian atmosphere and surface.

I have uploaded the model files and the web based processor for the Tiny Pocket Spectrometer, including source files and the case.

The model is using the Spreadsheet feature of FreeCAD to provide parametric changes.

Screenshot of the Tiny Pocket Spectrometer in FreeCAD, showing 3 versions and the spreadsheet controlling the parameters.

$The Tiny Pocket Spectrometer 3D printed and painted black with spray paint. Also the part of the DVD that servers as the diffraction grating.$

The web interface, spectro-web, used with the Tiny Pocket Spectrometer.

I built a thing, which can do things!

I'm also great at documentation.

#spectrometer

The web based analyzer for the spectrometer is coming together, although I still have to figure out a few things. This screencapture shows a few of the features, but nothing serious, just sliding the sliders and buttoning the buttons, then cycling through a few colors on the lamp in front of the phone.

It's still WIP but you can try it here: https://gheja.github.io/spectro-web/src/

I started to work on a mini pocket spectrograph, the 3D model will be available for download, I just need to tune a few things.

I am also working on a little web based stuff to make sense of the things seen, strictly locally in the browser, on the client side.

It's a fun random side project, though I already bought about 8 different light bulbs just to see their spectrum...

Project 2, supervised by @fbenitez.bsky.social:

Identification of native vegetation species by linking UAV imagery with terrestrial spectroradiometers
https://iapetus2.ac.uk/studentships/identification-of-native-vegetation-species-by-linking-uav-imagery-with-terrestrial-spectroradiometers/

This project will develop accurate and efficient spatial data science methods to classify and monitor native vegetation species in subtropical regions from #UAV #multispectral #imagery and field #spectrometer data.

screen capture - Video feed of Tanager-1 satellite deployment

satellite image - This methane plume was captured south of Midland, Texas, in the Permian Basin, one of the world’s largest oil fields. The imaging spectrometer on the Carbon Mapper Coalition’s Tanager-1 satellite made the detection on Sept. 24. 2024

satellite image - On Sept. 19. 2024, the imaging spectrometer on the Carbon Mapper Coalition’s Tanager-1 satellite detected this methane plume in Karachi, Pakistan, extending nearly 2½ miles (4 kilometers) from a landfill.

satellite image - Extending about 2 miles (3 kilometers) from a coal-fired power plant, this carbon dioxide plume in Kendal, South Africa, was captured Sept. 19 by the imaging spectrometer on the Carbon Mapper Coalition’s Tanager-1 satellite.

Quastion to the #science community.
Anyone has any recommendations for an affordable color absorption #spectrometer or a kit / open source manual to build one?

Random spectrum to make my post more visible.

[#ExoMars : report and update] The postponement of the ExoMars mission has given IRAP scientists the opportunity to update some of the components of the #Raman laser #spectrometer.

The spectrometer will analyse #samples taken from beneath the surface of #Mars that have been ground and powdered beforehand. It will be able to identify the #organic compounds present and will contribute to the search for #microbial life.

Launch scheduled for October 2028! Stay tuned 😜
