Mötesplats Rydberg - Laser Remote Microscopy on Biological Lidar Targets

Laser Remote Microscopy on Biological Lidar Targets

With Mikkel Brydegaard, Senior lecturer at Combustion Physics , Department of Physics.

Abstract
Conventional wisdom dictates that we should use shortest wavelengths and largest numerical aperture to observe tiny features - but what could a spectroscopist see by doing the opposite? Yes, we can deduce elements and picometer electron shell spacings in the solar atmosphere a gigameter away thanks to atomic transitions. But, we could also deduce millimeter snow grain size from satellites from the incoherent reflectance. I will demonstrate highlights from our group where we use infrared laser remote sensing to deduce axial structural features with nanometer resolution and lateral surface roughness in micrometers. It is even possible to deduce microscopic eggs inside mosquitoes with a single wavelength. I will speculate on future advances where we may be able to assess nanosomic hair growth on mosquitoes or virus inside them. Advances with applications for estimating disease transmission and biodiversity.
