Deep learning is a class of machine learning techniques that use multilayered artificial neural networks for automated analysis of signals or data. The name comes from the general structure of deep neural networks, which consist of several layers of artificial neurons, each performing a nonlinear operation, stacked over each other. Beyond mainstream applications, such as the recognition and labeling of specific features in images, deep learning holds numerous opportunities for revolutionizing image formation, reconstruction, and sensing fields. In fact, deep learning is quite powerful and has been surprising optics researchers with what it can achieve for advancing optical microscopy and introducing new image reconstruction and transformation methods. Physics-inspired optical designs and devices are moving toward data-driven designs that will holistically change optical hardware and software of next-generation microscopy and sensing, blending the two in new ways.
Aydogan Ozcan samples an image and then acts on it using a computer. Powered by deep learning, next-generation optical microscopes and sensors understand a scene or an object and accordingly decide how and what to sample based on a given task. This requires a perfect marriage of deep learning with new optical microscopy hardware that is designed based on data. For such a thinking microscope, unsupervised learning would be the key to scale up its impact on various areas of science and engineering, in which access to labeled image data may not be immediately available or may be costly and difficult to acquire. Ozcan provides an overview of recent work on the use of deep neural networks in advancing computational microscopy and sensing systems and covers their biomedical applications.
