Optical technologies have contributed to significant advances in the medical arena. Ultra-high resolution images of the brain, eye and vascular system have significantly advanced our understanding of the operation and function of these systems. Therapeutic lasers techniques improved the vision of millions of people. Advances in microscopy, spectroscopy and nanotechnology continue to enable us to reach new possibilities for in situ diagnostics. Many challenges face society calling for new, innovative and affordable technology solutions.
The 2022 winners of the Optica Foundation Challenge in the health category will present their progress along with a special keynote.
The optical implementation of neural networks can be advantageous compared to electronics in terms of power consumption. This derives from the fact that the energy required to transmit information optically can be nearly independent of the distance between the emitter and the receiver. Consequently, optics can be particularly suitable for hardware implementations of neural networks due to the dense connectivity of neural architectures. Neural networks, however, use the strengths of the interconnections between the processing units (the “neurons”) as computing and storage elements. An optical neural network must therefore include a mechanism that allows it to be programmed or trained by modifying the strength of the interconnections. In this presentation we will review optical methods and also present recent results for programming optical learning machines implemented with multi-mode fibers.
