Innovative Design Process Fastracks UAV Laser Comms Development

Using photonics technologies to establish communications in air-to-ground, air-to-air, and air-to-space fields offers many advantages related to transmission speed, low size weight and power (SWaP) systems, spectrum regulations, and immunity to electromagnetic interference. This article discusses the additional advantages of using photonics in the design process of UAV laser comms development, and provides an example of a UAV laser transmitter under testing at Gooch & Housego.

Precision Explosives Analysis Using High-Speed Imaging
By Vilem Petr, Colorado School of Mines, and Philip Taylor and Gene Nepomuceno, Vision Research

High-speed imaging can be used to quantitatively capture explosions, the resulting damage, and to measure other important parameters of the explosion. The data collected can provide information to aid in the understanding and characterization of a detonation, which can then lead to the creation of better and more precise explosives.

Spotlight On Optical Manufacturing
Neutral Density Filters

Hoya’s neutral density filters have nearly even spectral transmittance in the visible region and are classified by the average transmittance within wavelengths from 400 nm through 700 nm. These filters are able to control light intensity without selectively absorbing light with a specific wavelength.

The Seductive Siren Call Of The “Megapixel Lens” (And Why You Shouldn’t Listen To It)

In response to the popularity of megapixel cameras and sensors, many lens manufacturers are marketing "megapixel lenses." The problem? There's no such thing.

Alkali-Free Boro-Aluminosilicate Glass

Highly transmissive, thin, alkali-free, boro-aluminosilicate glass from Asahi Glass Corporation (AGC) is designed for use in highly sensitive bio-photo detection applications, high-throughput sensor applications, as enhancement glass for thin displays, and as cover glass for micro arrays.

Direct Imaging Of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral Imaging

Many types of natural gas from shale formations are odorless, colorless, and highly flammable, and leaks/emanations are important considerations for safety and the environment. This application note illustrates the benefits of using an imager at a site where shale gas leaks unexpectedly happened.

Comparing Fields Of View

There can be many factors to deal with when looking to utilize the best field of view (FOV). This white paper covers the different types of FOV, the factors that must be considered for choosing a lens for FOV, and what lens focus does to FOV.

Reducing Expenditure, Optimizing Workflow, And Keeping Downtimes Low With High-Speed Rugged Cameras

PCO has launched a new high-speed series of pco.dimax cs cameras, adding three new models to its portfolio. These new models are compact, ruggedized, and targeted for on- and off-board crash test applications.
