APPLICATIONS & TECHNIQUES

MATERIALS TESTING

High-speed imaging is applied to materials testing in order to measure the physical and mechanical properties of different materials or components. Typical testing methods include: Tensile Testing, Drop Testing, Compression, Deformation, Crush Resistance, Delamination and many more. 

Photron high-speed cameras have been designed to meet the requirements of specialized analysis techniques employed in materials testing including Digital Image Correlation (DIC).

FLUID DYNAMICS

In fluid dynamics, high-speed imaging provides an indispensable tool to measure and to visualize the complex behavior of liquids, gases and plasmas in motion. Photron high-speed cameras have been designed to meet the requirements of specialized imaging techniques employed in fluid dynamics including Particle Image Velocimetry (PIV), laser Induced Fluorescence (LIF) and others.

BALLISTICS, IMPACT PHYSICS & DETONICS

High-speed camera analysis is utilized to understand and characterize events in interior, intermediate and terminal ballistics research. When studying projectile launch and inflight behavior, blast protection and personal armor development, high-speed imaging plays a vital role. 

COMBUSTION

Driven by the requirements of increased efficiency and environmental protection, high-speed imaging has become a key technology in the development of cleaner and more effective combustion processes. Due to the complex and turbulent nature of combustion events, high-speed cameras play a vital role in both qualitative and quantitative analysis.

AUTOMOTIVE CRASH TESTING

High-speed image analysis is now an essential component of automotive safety testing. High-speed cameras are utilized within both on-board and off-board testing in a wide variety of tests including Frontal and Rear-end Impacts, Side Impacts, Roll-over Tests, Sled Tests, Airbag and Seatbelt Testing and more.

R&D

New product design and development is a crucial factor in the success of any organization. The utilization of new and innovative materials and processes requires a complete understanding of events that are too fast for the eye to see. High-speed imaging allows engineers and scientists to visualize, measure and characterize complex industrial processes and experimental scientific research.

TECHNIQUES

DIGITAL IMAGE CORRELATION

DIC is a 2D or 3D optical tracking technique used to measure deformation, viberation and strain in materials. Photron high-speed cameras are utilized by all DIC system integrators worldwide.

BACK ILLUMINATED IMAGING

Backlight and shadowgraphy are widely used imaging techniques. Under the correct conditions, these techniques can provide high contrast images of objects particularly in fluid dynamics imaging.

LASER ILLUMINATION

The sort pulse widths, narrow spectral range and high light intensity offered by laser light sources provides the opportunity for unique imaging techniques when combined with high-speed cameras.

SCHLIEREN

Schlieren imaging is used as a means of visualizing changes in pressure, temperature and shock waves in a transparent medium such as air. In applications such as wind-tunnels and pressure chambers schlieren imaging provides clear and detailed information on changes of pressure and density.

PARTICAL IMAGE VELOCIMETRY

Particle Image Velocimetry, otherwise known as PIV,  is an optical method widely used in flow visualization and fluid dynamics research. PIV provides detailed measurements of velocities, vectors and related properties in fluids.
