Laser Illumination For High-Speed Imaging
By Photron, Inc.

An incorrect or poorly lit subject affects the image, regardless of camera system quality. Therefore, the illumination source is just as important as the camera's resolution and sensitivity. See how a laser can be used for illumination in these four high-speed imaging application examples.

Spotlight On Remote Sensing
Hyperspectral Imagers

The new OCI-F Series from BaySpec is made up of miniature push-broom hyperspectral imaging cameras covering the VNIR (400 - 1000 nm) wavelength ranges. The ultra-compact designs, simple operation, and intuitive software make these cameras ideal for many spectroscopy applications.

Avalanche Photodiodes For LIDAR Applications

Avalanche Photodiodes (APD)  are ideal for laser-based distance measurement, laser scanning and mapping, shape recognition and remote sensing, as well as LIDAR (Light Detection and Ranging). APDs also excel in applications with very low optical signal strength or with high modulation frequencies.

Volcanic Eruption Observations From An Elevated Point Of Stromboli Using Thermal Infrared Hyperspectral Imaging

Research on different indicators of imminent volcanic eruptions is carried out on an ongoing basis, especially with volcanoes located close to urban areas. This app. note highlights the benefits of using standoff infrared hyperspectral imaging for characterizing volcanic process.

Multi-Zone Filters

Iridian Spectral Technologies' multi-zone filters offer spatially varying spectral performance on a single substrate in the UV to LWIR wavelength range. Filter types include bandpass, notch, long-pass, and short-pass with coatings offered for AR, high-reflectivity, and black-absorbing.

Barle High-Resolution 25 mm SWIR Lens

Gooch & Housego's new 25 mm Barle high-resolution lens, for use with short wave infrared cameras, offers optimal SWIR imagery for machine vision and security applications, including remote sensing, fog penetration, and night vision.

Optical Solutions For Defense And Aerospace Applications

From applications under the sea to those orbiting the Earth, ZYGO creates the highest quality products with challenging specifications in extreme operating environments. From prototype to production volumes, ZYGO provides program management, engineering design, and manufacturing support.

Explosives Engineering: High Speed Imagery For Research And Experimentation

Vision Research is in collaboration with the Colorado School of Mines in order to develop a university-level short course on the use and benefits of high-speed imaging, while experimenting with explosives and ballistic applications.

Math, Magic And MTF: A Cheat Sheet For The Vision System Community

MTF is the best proxy for lens performance, but the math behind it and the graphs that depict it often obstruct understanding. This paper demystifies MTF, arming vision system decision makers with the knowledge they need about it to choose the right lens every time.

Automation And Microscopy: Faster Test And Measurement

Nanotechnology uses the concept that constant velocity will get you to the destination faster than constantly stopped traffic. One technique puts this concept into practice via a fast nano-focus device based on a piezo-ceramic actuator embedded in a flexure guided lens positioning mechanism.

Ultraviolet Transmitting, Visible Absorbing Filters

Hoya offers dark glass (nearly black) filters that are capable of transmitting the ultraviolet region and absorbing the visible region. These filters are ideal for single extraction of ultraviolet rays, and are often utilized for selectively transmitting the 253.7 nm and 365 nm wavelengths.
