Near Infrared Light Sensors

Other Hardware Sensors
1

Dear all,

I am new, not only to the Fora but also to the Arduino world. I look forward to getting up to speed in the coming months and even years, if this is what I need for my project. This is a brief summary:

I need to measure infrared wavelength emissions and store them in a database for further analysis. Discrete values ranging around 1000nm. I would need, say, 100 measurements for second. The more, the better in fact.

Is this doable with arduino o should I better look for other options. This is for a in principle low budget project, which may change if I see I am getting some positive results. So, would such sensor be available at a reasonable price? Reasonable to us is under $ 100.

Thanks in advance to all of you, it is great to be here and I look forward to hearing ideas or remarks.

What do you want to measure?

Thanks for your question!

Wavelength values of laser light reflecting on a number metals.

4

Laser light is a single, fixed wavelength. You're going to use multiple lasers or so?

5

It is expected it will change frequencies as it bounces back from the metal. Disregarding the physical phenomena, do you think such a measuring and recording device could rebuilt with Arduino?

6

For lack of fluorescence and phosphorescence by most metals I don't see how this could happen, especially in near-IR.

Do you have a sensor in mind that can take the reading of the returned frequency? All an Arduino can do is get the data from that sensor.

The frequency will only change if the metal is moving. Doppler effect.

Are you wanting an optical spectrum analyzer / spectrometer? Have you see this: https://spectralworkbench.org/

I suspect its more complicated than that - for instance you'd need to understand nanophotonics quite well to
be able to say that for sure...

Thanks, MarkT, I was looking for something like that indeed. It works with Raspberry Pi but it is still great. Could i be used with an Arduino? Please excuse my ignorance.
