This short course aims to give researchers background and the state of the art developments in the field of biomedical sensing and super resolution. In the first part dealing with biomedical sensing I will present a technological platform that can be used for remote sensing of biomedical parameters as well as for establishing a directional communication channel. The technology is based upon illuminating a surface with a laser and then using an imaging camera to perform temporal and spatial tracking of secondary speckle patterns in order to have nano metric accurate estimation of the movement of the back reflecting surface. If the back reflecting surface is a skin located close to main blood arteries then biomedical monitoring can be realized. If the surface is close to our neck or head then a directional communication channel can be established. I will talk about the implementation of this technology for remote and continuous estimation of heart beats, respiration, blood pulse pressure, intra ocular pressure, estimation of alcohol and glucose concentrations in blood stream, blood coagulation and oxymetry.

The second part deals with recent novel approaches in the field of optical super resolution for near and far imaging. Digital imaging systems as well as human vision system have limited capability for separation of spatial features. Therefore, the imaging resolution is limited. The reasons to this limitation are related to the effect of diffraction i.e. the finite dimensions of the imaging optics, the geometry of the sensing array and its sensitivity as well as the axial position of the object itself which may be out of focus. In my course I will present novel photonic approaches and means to exceed the above mentioned limitations existing in the vision science and eventually to allow us having super resolved imaging providing improved lateral and axial capabilities for separation of spatial features.
