JUSTINE MURPHY, SENIOR EDITOR, [email protected]For all of their diversity of form and function, the vast range of available optical components and optical fibers have much in common — materials, engineering and design, and techniques in fabrication and metrology. And they are among the critical enabling technologies of the future. Today, optical technologies are integral to sensors, microscopes, lasers, cameras and more, and the list keeps growing. They are employed by the military for field detection in submarines and IR imaging on the battlefield. They can be found on factory floors and in surgical suites. The continuing...Read full articleRelated content from Photonics MediaARTICLESImager Could Help Autonomous Vehicles See Around CornersAn around-the-corner camera system built by engineers at Stanford University uses a wave-based image formation model to allow non-line-of-sight (NLOS) imaging.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookInfrared Spectral Selection: It Begins with the Detector: An IR imaging system employing a narrow spectral band brings hidden images to light, broadening IR imaging’s applications.Spectral selection is a powerful tool that enhances conventional imaging tremendously.
