3D Machine Vision: One Small Step For Robots, A Giant Leap For Factory Automation
By Naomi Shisaike, Canon

The introduction of 3D machine vision systems to automation processing overcomes the technological hurdles of machines being able to “see,” analyze, and make decisions in an unpredictable environment. Designed specifically for factory work, these new machines meet production requirements of high accuracy, speed, and low maintenance while also being durable enough to withstand factory conditions.

Spotlight On Non-Destructive Testing
Nondestructive Testing Of Mid-IR Optical Fiber Using Infrared Imaging

Some materials used in the manufacture of optical fiber lasers cannot have any defects if the laser system is to be efficient. This app note shows how infrared imaging can be used to carry out NDT of optical fiber integrity. The methodology allows the screening of tens of meters in just a few seconds.

Cooled Mid-Wave Infrared Camera: Tigris-640

The Tigris-640 is a cooled mid-wave infrared (MWIR) camera with a resolution of 640 x 512 pixels and a pixel pitch of 15 µm that is ideally used for biomedical, industrial process monitoring, nondestructive testing, MWIR R&D, and thermography applications. It is available with an MCT or InSb detector, as well as a broadband option that permits for the increase of sensitivity of the camera into the SWIR wavelengths.

Why SWIR And InGaAs Are Useful

Sensing in the shortwave infrared (SWIR) range (wavelengths from 0.9 to 1.7 microns) has been made practical by the development of indium gallium arsenide (InGaAs) sensors. Sensors Unlimited has used SWIR and InGaAs technologies for over 25 years, and has designed and manufactured integrated solutions to the commercial, business, and military industries. This white paper covers the importance of using InGaAs technologies in SWIR applications and discusses why it is worth going through all the trouble for its uses.

High-Resolution, LWIR, Scientific-Grade Infrared Camera: FLIR A655sc

FLIR's A655sc infrared cameras offer ultra-sharp 640 x 480 image resolution, high-speed windowing for an increased output frame rate up to 200 Hz, Gigabit Ethernet and USB connectivity, filtering, and the best sensitivity in an uncooled sensor. With its uncooled detector, high resolution, and all of the cutting-edge functionality scientists and researchers have come to expect from FLIR, the A655sc Series brings affordable research and scientific thermal imaging and measurement to a whole new level.

Understanding A Camera's Dynamic Range

The “intra-scene dynamic” of a camera system is its ability to measure and distinguish different levels of light. Most camera manufacturers refer to the term as dynamic or dynamic range in their technical data sheets. In addition, the dynamic range in photography is equivalent to the contrast range. Since many camera manufacturers define dynamic range from a different point of view, a distinction should be made between the “dynamic range of an sCMOS, CMOS, or CCD image sensor,” “dynamic range of an analog-to-digital-conversion,” “usable dynamic range,” and “maximum dynamic range or SNR.” This article defines the different points of view for the dynamic range of camera systems and discusses when each term should be used.

DeepView OCT Series Spectrometer Engines

The DeepView OCT series comprises both shortwave-infrared (SWIR) and near-infrared (NIR) spectrometer engines that utilize optical coherence tomography (OCT), white light interferometry (WLI), or infrared spectroscopy.

Advanced-Absorber Microbolometer Superstructure: Patented Sensor Technology Revealed

The most significant development in the production of infrared sensors and their ability to affect improvements to SWaP-C requirements comes from the introduction of uncooled focal plane array (FPA) designs. 

Using 6-Axis Hexapod Motion Platforms In Dental Research

As hexapod motion and positioning platforms become more mainstream technologies, their applications have expanded into medical fields such as dental biomechanics. The growth into these new dental applications and research requires a solution for the challenges in dealing with the combinations of small forces with large deflections, as well as large forces and extremely small deflections. In order to deal with this challenge, the HexMeS (Hexapod Measuring System) was designed. This article details the use of the HexMeS and highlights the key reasons for choosing hexapod motion systems in dental research applications.

Image Resolution Comparisons

In thermal imaging, it is difficult to overcome the challenges of fewer pixels and lower resolution. As a solution, Sierra-Olympic offers arrays with 320 x 240 resolution and up.
