About This Webinar
This webinar will introduce you to the enormous potential of computational imaging for a range of industries, from manufacturing to machine vision to biophotonics. Professor Rajesh Menon and his group from the University of Utah have demonstrated several examples of computational imaging, which will be discussed during this webinar.

First is a “see-through” camera, comprised of a transparent window with an image sensor placed facing into the edge of the window. In this lensless camera, the image and field of view are optimized not through a lens, but through a careful selection of geometric parameters and training of a neural network, enabling highly compact and private imaging systems. Next is a snapshot hyperspectral imaging camera, whose spatial and spectral performance can be programmed without any change in the hardware. Finally, an approach to deep-brain imaging that utilizes only an ultrathin surgical needle to transport light in and out of a mouse brain. In all cases, imaging is essentially a form of information transfer enabling highly nonintuitive forms of imaging.

Menon will discuss the underlying technologies and their limitations. He will discuss additional potential applications for lensless cameras, including in augmented reality and security, and techniques such as application-specific imaging that can make lensless cameras more efficient than traditional imaging technologies. He will also address the broader field of computational optics.
