 Alright, so the first, I'm going to tell the first three speakers. We're going to start off with Robbie you have both thing from University of Cape Coast Ghana. Then we'll go to Ricardo Gallego to roll me. And I'm not sure because I don't see where you're from on the on the sheet here. Lou Rue, Hugh who just asked a question. All right, so those are the first three speakers. So I'm going to start off with Robbie. Robbie, you can go ahead and start. If you got two things open, it's going to be back. Yeah. Hello. And hello. Yeah, so this is Andrew. I'm presenting with Robbie. We are using the same setup. But we are working on two different things. And so I'm going to talk about mine. And then he talks about his same presentation. And so a background to our presentation. So what I'm going to talk about is that's the remote sensing group in Lund. I've designed a 3d printer. A 3d printed fluorescence hyperspectral. And the setup is based on a slamfack principle, which is able to produce a data cube of this nature, something which will give you data in the spectral range and also in terms of spectrum and also in terms of range and time as well. And so in the course of March, they came to Cape Coast to train us for close to one month on how to go about this. So we worked on printing a set up of that nature over here. And then they helped us with the setting it up. And afterwards, we have been trying our hands on different experiments with it. In my case, I am studying different types of insects with the fluorescence slider. And the expectation is that would be able to monitor vectors like mosquitoes, house flies, which are pests or which are, which carry parasites and then honey bees, which are also beneficial. And because it's a fluorescence slider, sometimes you have to tag the insects before we can do the monitoring. This is how a setup looks like. And over here we have the, the fluorescence slider over here. And then a system or a cage where we put the insects over there for laboratory measurements. And so light is incident into this box to interact with the samples and then we're able to get feedback into the system again. Now, when the insects are untagged, we don't put a filter in the, so that we can be able to obtain elastic signals at various times for us to know, and then at various ranges. And then when the insects are tagged to us, well, we are able to put a filter in there and observe which, which, which insects is there depending on the type for the, for instance, this is within the red region. And so it is one of the colored tax in that region. And so this is going to be helpful for us in doing works of this nature. Robbie is going to talk about the ones for vegetation. Okay. Okay. So for my aspect, okay. So we, after employing the fluorescence slider on the, on the vector is also used for vegetation. And for this time around, we are trying to measure, do some remote measuring on some plant species. So this one is a purple. And this time around we have a fluorescence. The 405 is a 405 millimeter. That's used to we have it hitting at the back of some part of the, of the leaf. And we have to use the, the light hitting at the back of the leaf and get some fluorescence back and measured it. So after getting the fluorescence, we have some structures like this. So this part this time around, the red dotted red that you see, it's a different, different, different parts of the leaves that we're trying to see how it can really differentiate some different parts of it. So we hit it. We targeted a green part of it and also a very dry part. So let's say a healthy one, healthy one. And so the red one is what we have there. And the black one is for the, was for the green one. And then the dotted red was the one that it was having a little yellowish side of it. So apart from this one too, we are trying to see if this thing can also be used for range measurements. So should in case you want to measure a particular plant, some different plant species and a particular distance. So we're trying to see how effective the system can also measure with a wavelength and also with range. So we are, we are still on it. There are a lot of things that are still measuring and we are, we are hoping for a further system. So other uses that we are thinking of is also doing the demonstration in different aspects of the process like that. And also interact with students on how effective you can use this one. And also doing an internal or external collaborations on the process like that too. Okay. So thank you very much. Okay. Thanks. So, so that was, those are the two talks between Andrew, you and then Robbie that. That right. Yes. Okay. Great. We're really on time. Anybody have any questions? Joe, do you want to ask anything? There we go. Now I can. I don't know that I have a specific question, but I, I, I mean, I'm pleased to see this. I know, I know this paper. I know the instrument and I know that. The, the, the, the, the, the, the, the, the, the, the, the, the, the record's group and Sweden is collaborating globally. So this is really, this is really fascinating. I would, I would encourage you though in this kind of presentation to really hit the. The key points. Maybe with fewer details, you're, you're still kind of in that. Scientist engineer mode of presenting. who's there ready to fund you and all the information is there but you need to pick out just the important one. This is remarkable how much I guess one question I would have is is I am. I believe that I understand that there is a very low cost for this do you know what it would cost to reproduce one of these systems, the 3D printed systems. Yes. So they, depending on the kind of lasers that you want to use and the detectors that may raise the cost but with close to $1,000 you could be able to get $100 laser and then maybe a less costly detector or something like that. But if you want a very expensive detector, then it may raise the cost from that the instrumentation or the printing and other other things are not that close. That's really incredible isn't that's fabulous. Thank you. Okay. Well, at least how Randy, do you have a question. Yeah, what is the, what is your resolution and range. How far can you go. Cross range and distance how what are the range resolutions. Yeah, so the range resolution and it's going to go up to 100 meters. And so in the data cube. They can go up to 100 cube from five meters from the onset away from the source and then 100 meters away to the end. And is it, is it scanned left. Is it scanned or how do you how do you get cross range. Or is it just. Yeah. No, it is not scan so within the range. You can. So within the range, depending on whether anything crosses in between it can be able to tell which point it's crosses that. It's fixed and then you look at objects that goes through by just kind of then it means that it is going to be based on the time frame. So that's if. So your three axes are time frequency and range of time wavelength and range, I guess. Yeah, I think we. We lose Andrew. No, I think he's online. Anyway, let's maybe maybe we should move on to the next speaker. Yeah. We got, we got seven more. Okay. Well thank you very much, Robbie and Andrew that was. Everybody else paid attention to what Joe just said.
