competing technologies or you know peer technologies a natural question is why is this technology so exciting well this is probably the only technology that allows us to image from organelles all the way to organs in vivo and we use the same contrast right so we use the optic absorption as the contrast mechanism so I'm plotting different implementations of this technology right we actually have far more than that can pot here but this says this is a highly scalable technology we can image at very much microscopic level but we can also scale
