EXETER, England, Nov. 8, 2019 — Satellite-based Earth observation is key to globally monitoring oceanic carbon absorption levels, according to a study led by researchers at the University of Exeter. Satellites originally launched to study the wind also have the capability to observe how rain, wind, waves, foam, and...Read full articleRelated content from Photonics MediaARTICLESRIT Professor to Develop Diffractive Solar SailsA new approach to solar sail design using diffractive optics could enable spacecraft to photograph the poles of the sun for the first time.

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 HandbookUltraviolet Reflectance Imaging: Applications: 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 UV band. Digital ultraviolet imaging is becoming increasingly affordable and lends itself to a number of interesting applications that have been largely overlooked, and digital sensors are available that span the UV spectrum from 200 to 400 nm.Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...Photonics HandbookPassive Athermalization: Maintaining Optical Performance Over Temperature: An optical system is athermalized if its critical performance parameters (such as modulation transfer function, back focal length and effective focal length, etc.) do not change appreciably over the operating temperature range.For rotationally symmetric optical systems, either the lens or the detector moves along the optical axis to maintain optical performance. If the compensating axial motion is accomplished without the...Photonics HandbookWHITEPAPERSSWIR Camera Test – The New Swux UnitSWIR imaging technology based on InGaAs sensor products has been a staple of scientific sensing for decades.
