I wonder how essential for the experiment is to keep the target in 410nm domain.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-45799707953799193302018-01-08T05:57:53.139+02:002018-01-08T05:57:53.139+02:00The light that interacts with the target is 405 nm...The light that interacts with the target is 405 nm. (\Sigma_0 as shown in figure 1) It isn't converted to NIR until after it has passed through the target, so it gives the same image as a conventional 405nm imager would produce.

Shine 405 nm light on the target<br />2. Convert the light to 810 nm<br />3. Do some quantum magic<br />4. Get an image that is better than they would expect for 810 nm imaging, and almost as good as they would expect for 405 nm imaging.<br /><br />Cool and interesting, but it seems like they are doing a lot of work with no practical advantage over just imaging at 405 nm. Am I missing something?<br />Viaddhttps://www.blogger.com/profile/05455283796086963452noreply@blogger.com
