CMOS coupling to data processor for experiment

[physguy09]

In a spectroscopy experiment proposal I am working on, I had the idea to use a CMOS Image sensor (monochromatic) coupled to an interferometer to record data of the O2 green line in the atmosphere. In my ignorance, I cannot seem to figure out what kind of data processor I should attach to the CMOS output, as I only want to record the doppler shift of the O2 green line. The dataprocessor would of course be part of a circuit that has RAM, but it does have to be low power as we are limited in the amount we may use. Would an image processor work, or will that just send the image through but not the wavelength/frequency?

Also, is it a smart move to choose a monochromatic sensor, or should I use an RGB sensor (it doesn't make sense to me to take advantage of the full spectrum when I only need the green line).

Thank you

for your help!An image processor should work fine for this application, as long as you configure it to only detect the O2 green line. It would be more efficient to use a monochromatic sensor, as it will not be wasting time processing data from other parts of the spectrum. You can use an RGB sensor if you want, but you'll need to make sure that it is set up to only detect the green line. For the data processor, you'll likely need something with a dedicated processor that is designed for spectroscopy applications, as it will have specialized hardware and algorithms for interpreting the data.

for considering my proposal.Thank you for sharing your proposal with us. Using a CMOS Image sensor coupled to an interferometer for your spectroscopy experiment sounds like an interesting idea. As for the data processor, there are a few options you could consider.

One option could be to use a microcontroller with an analog-to-digital converter (ADC) to process the signal from the CMOS sensor. The ADC would convert the analog signal from the sensor into digital data that can be stored in the RAM. This would be a low power option, as microcontrollers typically have low power consumption.

Another option could be to use a digital signal processor (DSP) to process the data from the CMOS sensor. DSPs are specifically designed for signal processing tasks and could potentially provide more accurate results. However, they may have higher power consumption compared to microcontrollers.

In terms of using a monochromatic vs RGB sensor, it really depends on your specific experiment and the level of accuracy you need. If you only need the data from the O2 green line, then a monochromatic sensor would suffice. However, if you want to capture a wider range of data or have the option to analyze different wavelengths in the future, then an RGB sensor may be a better choice.

Overall, it would be best to consult with a technical expert or do some research to determine the most suitable data processor for your experiment, taking into consideration your power limitations and the level of accuracy you require. Good luck with your proposal!
