Optical Imaging and Sensing

Understand the future of optical imaging with this cutting-edge guide

Optoelectronic devices for imaging and sensing are among the backbones of modern technology. Facilitating the mutual conversion of optical and electrical signals, they have applications from telecommunications to molecular spectroscopy, and their incorporation into photon-involved technologies is only growing. The rapid development of this field makes the need for a fully up-to-date introduction all the more critical.

Optical Imaging and Sensing meets this need with a comprehensive guide to the novel materials and devices employed in optical imaging and sensing. Given the current revolution in new imaging materials, an introduction that fully incorporates the latest research is an indispensable tool for scientists and engineers in a huge range of fields. The technologies surveyed here promise to transform public security, 5G and next-generation wireless communication, clinical imaging, and many more.

Optical Imaging and Sensing Readers will also find:

• Detailed discussion of materials including semimetallic graphene, semiconducting black phosphorous, and many more
• Discussion of devices from infrared photodetectors to nonlinear interferometers
• A thorough look forward to the future of the field

Optical Imaging and Sensing is a useful reference for materials scientists, spectroscopists, semiconductor physicists, and engineers working in any field or industry involving optical imaging or sensing technology.
