Three Things To Consider Before Purchasing A High-Speed Camera
By Gene Nepomuceno, field applications engineer

At Photonics West 2017, Gene Nepomuceno spent a few minutes discussing the three main factors one should take into account before selecting a high-speed camera — resolution, frame rate, and sensitivity (with an honorable mention for transferring the data off of the camera).

High-Speed Cameras Help Digital Image Correlation Show Its Strength
By Nicholas Long, OEM manager, and
Doreen Clark, sr. product manager

The popularity of digital image correlation (DIC) is growing, especially in the aerospace, defense, and automotive industries where DIC is used to test the strength, stress, strain, and load response of various parts and materials. This paper discusses how high-speed cameras and various software packages are helping DIC expand into new applications while also ensuring the technique delivers quality quantitative data through noncontact testing.

Advancing Microfluidics Research Using High-Speed Cameras
By Nicholas Long, OEM manager

Microfluidics research involves controlling and studying small amounts of liquid, often confined to channels as small as tens of microns wide. With a growing field of microfluidic applications, high-speed camera systems are utilized for accurate analysis of the quickly changing micro-scale fluid dynamics. This article discusses using high-speed cameras for microfluidic data acquisition.

Outcomes Of Mid-Air Collisions Between Drops And Solid Particles

The study of drop-particle collisions involves examining the outcome of the impact of a particle on to a drop of liquid in mid-air. In applications such as tablet coating in the pharmaceutical industry, or the refining of heavy crude oil in fluid catalytic cracking, the information gleaned from this experiment is vital.

The Heat Is On: Examining Two-Phase Flow And Heat Transfer With High-Speed Cameras

We rely on air conditioning and refrigeration to operate through a heat exchanger — a transfer of heat between one or more fluids, essentially increasing heating and cooling efficiency and flow. A group of Pennsylvania State University students is studying two-phase flow and heat transfer phenomena in an effort to advance these processes and their technologies.
