Applications
Combustion
A high-sensitivity, high-resolution high-speed camera can be used to observe combustion (direct imaging, blue frame, spectral measurement).
The temperature analysis system using two color method can also be used to calculate the combustion temperature from the video footage.
Material Testing
The use of a high-sensitivity, high-resolution high-speed camera allows to observe the deformation of materials during high-speed tensile test and material destruction test in time series.
DIC (Digital Image Correlation)
The system principle of DIC (Digital Image Correlation) is based on Triangulation and Photogrammetry. It enables to analyze 3D surface coordinate from the distance and angle between 2 cameras. And the strain of the entire surface can be measured from capturing random patterns applied to the object. Three-dimensional coordinates of the material surface, displacement and velocity in three-dimensional space, maximum/minimum strain and strain rate can be calculated from images taken with a high-speed camera and DIC analysis software.
Explosion
A high-sensitivity, high-resolution high-speed camera can be used to observe explosion. The explosions can be observed in time series as EV battery explosion test, material destruction test and ballistic test, etc.
Fluid Dynamics
PIV (Particle Image Velocimetry) is the fluid measurement method that enables non-contact determination of velocity and direction in a two-dimensional plane using particle images of tracer particles mixed in the fluid. And method of Schlieren imaging which visualises the phenomena of density differences caused by temperature and pressure changes, etc and this optical system can be analyzed and observed flow in air. High-speed cameras are used in many situations of fluid dynamics, such as flow analysis in wind tunnel tests, combustion field flow analysis, spray propagation measurements and visualisation of shock waves.
Welding
High-speed cameras can be used to observe various welding phenomena that are normally invisible to the human eyes. It can be used to observe weld pools, spatter, solidification, etc., and it is useful to improve welding quality. In addition, synchronised shooting of waveform data and welding phenomena can be carried out. The temperature analysis system based on two color method can also be used to calculate the temperature on welding pool from the video footage.
Shock wave
High-speed phenomena such as shock waves can be observed by using high-sensitivity, high-resolution high-speed cameras. Shock waves are generated by various phenomena, such as explosions and supersonic flight. High-speed cameras is used in many fields related to shock wave as aerospace engineering.
Plasma
Plasma application research is done in various fields, including energy, aerospace and industrial sectors. High-speed cameras can be used to visualize fast-changing plasma behaviour. Combined with image intensifiers, etc., it is possible to capture ultraviolet emissions. And it is possible to measure multiple wavelengths simultaneously with a single camera using special optics that can extract specific wavelengths.
Automotive
Image measurement with high-speed cameras is essential in automotive crash tests to check the safety performance of vehicles. Multiple high-speed cameras are used to capture images of many parts including body deformation, dummy movement, airbag deployment and deformation of interior components. And image analysis software is used to calculate what is happening at any certain time and the amount of deformation during crash test.
Aerospace & Defense
High-sensitivity, high-resolution high-speed cameras are used in various fields, including aerospace and defense. High-speed cameras can be used in various studies, such as the observation of high-speed moveing objects at ballistic test, the behaviour of aircraft engines and the analysis of airflow around aircraft wings.
R&D
High-speed camara is used in many research and development field as deformation analysis of products in the drop test,visualization of wire bonding behavior, Inkjet and Jet dispenser, analysis of lithium-ion batteries and discharge phenomenon of electrical parts, etc.
Sports
When using a high-speed camera to analyse the movements of athlete and the behaviour of athletic equipment, detailed data can be obtained. While ordinary video cameras capture images at 30 fps, a high-speed camera can capture images from 500 fps to more than 10,000 fps. It is possible to get clear slow-motion images of dynamic muscles, the moment of impact on equipment, etc.
