Jan 18, 2017 — Superresolution optical microscopy has been one of the most momentous developments in the life sciences over the last decade — and its evolution is ongoing. Progress has been so rapid and significant that it has been dubbed by some observers as “the...

May 31, 2016 — There are three fundamental properties of light: intensity, wavelength, and polarization. Almost all cameras today are designed for monochrome or color imaging. A monochrome camera is used to measure the intensity of light over a broadband spectrum...

Mar 9, 2016 — Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before. These factors are motivating businesses in a widening range of...

Feb 16, 2016 — The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of absorption of light at a higher energy and subsequent...

Apr 27, 2015 — This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to...

Mar 8, 2009 — 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...

Mar 8, 2009 — The digital camera reflects a sea change in the compact camera market. While the 20th was the century of film cameras, the 21st belongs to the digital camera. The digital camera re...

Mar 8, 2009 — The demand for high-speed imaging has increased for a broad range of applications, from automotive crash testing to animal behavior to product component performance. There is a growing market for imaging systems that provides an immediate,...

Mar 8, 2009 — Spectral imaging has grown from an expensive research-oriented technique to one that is applicable for a wide range of scientific and industrial applications. This article looks at real-life systems, the arrangement of the instrumentation and...

Mar 8, 2009 — Through succeeding generations, image intensifying devices have brought vision to the dark of night. Image intensification, the basis of night vision, is a complex conversion of ene...

Mar 8, 2009 — Digital imaging provides the means to enhance features of interest while attenuating details that are irrelevant to a given application, and then extracts useful information about the scene from the enhanced image. Images are produced by many means:...

Mar 8, 2009 — 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. Most imaging systems, including the...

Mar 8, 2009 — The charge-injection device (CID) is a broadband (200 to 1100 nm) charge-transfer device (CTD) image sensor with capabilities well beyond the limitations of typical commercially...

Mar 8, 2009 — Ultraviolet imaging has long been thought to be difficult and awkward by many photographers because of the difficulties encountered when using photographic film in the near-UV...

Apr 13, 2006 — Reducing pixel size can increase a digital camera's performance. However, there are tradeoffs that need to be considered when going that route. In the search for ever-higher pixel counts for the digital still camera, it is clear that, if chip size...

Apr 13, 2006 — Imaging has long been used in industrial processes to measure, monitor, control, or otherwise manage the production of goods. The challenge to the process designer is to develop a tool that captures vivid and measurable contrast of the monitored...
