Benefits Of Acousto-Optic Devices For Operation With 2mm Fiber Lasers
By Gooch & Housego

Fiber lasers operating in the 2 µm region with a large mode area in an “eye safe” region of the spectrum are attractive to many applications such as laser machining and biomedical systems. This article discusses the important consideration of the choice of interaction medium, such as acousto-optic devices, especially for the polarization behavior of the device when used in a fiber system.

Thermal Imaging Cameras Allow Machines To Read Human Emotions

Scientists are researching how machines can understand human emotions through the use of thermal imaging. For Artificial Agents (AAs) to set up contingent emotional and psychophysiological interaction with humans, the automatic nervous system (ANS) must be monitored and translated efficiently. 

Microscopy Illumination

Stereo microscopes are used for life sciences, material sciences, and clinical routine industrial inspection tasks. The better the object is illuminated, the more details become visible in microscopy.

The Relationship Between Pixel Size And Sensitivity

PCO-TECH looks to debunk the myth that “large pixel image sensors are always more sensitive than small pixel sensors.” This article describes, in detail, the relationship between an image sensor’s pixel size and its sensitivity, and how each defines the quality of an image.

Comparison Of Scientific Cameras For Fluorescence Microscopy

Raptor Photonics recently compared the performance of four of their scientific cameras in fluorescence microscopy. Each camera utilized a different sensor technology, EMCCD, sCMOS, and CCD under similar conditions in order to find the advantages of each one.

The Right Piezo Transducers, Actuators, And Motor Drive Solutions For Medical Engineering

Numerous applications in medical engineering and life sciences have requirements for motion and positioning equipment. This article covers the basics of piezo technologies, and highlights its benefits for bio-medical applications.

Compact High-Speed Camera

The FASTCAM Mini UX50 high-speed camera is housed in a 120 mm x 120 mm x 90 mm body and weighs only 1.5 kg. It’s ideal for applications involving on- and off-board high-speed imaging in automotive safety, biomechanics, materials sciences, fluid dynamics, life sciences, and defense and aerospace research.

SWIR And The U-2

The U-2 spy plane is the leading reconnaissance platform for the United States. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light).

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.

Can Your Laser Micro Drilling System Do All This?

The recent introduction of a 5-axis laser micro drill system expands the limits of micrometer range drilling. Canon’s unique technology creates flexible hole shapes and wider angles at significantly higher processing speeds. Stent production, injector hole drilling, and micromachining will benefit.

Medical Device Quality Control
