Measurement of Fiber Board Poisson's Ratio using High-Speed Digital Camera

Speed measurement of spherical objects using an off-the-shelf digital camera

bstract. Motion blur is a result of finite acquisition time of practical ameras and the relative motion between the camera and moving bjects. We present a method for speed measurement of spherical bjects using motion blurred images captured by a digital camera. he object is assumed under a straight line uniform-velocity motion, nd the speed is calculated according to the imaging geometry and lu...

A quick-retrieval high-speed digital framing camera

A new high-speed digital framing camera is described. The design is built around a rotating polygon mirror that provides a framing rate of 24 000 frames/s. The camera electronics digitizes an image into a 32 x 104 grid of pixels, where the second dimension of the grid can be varied and is determined by the 8 bit computer-aided measurement and control digitizer sampling rate. Available digitizer...

High-Speed Solid State Camera Systems for Digital Photogrammetry

For many applications in machine vision, digital photogrammetry and scientific research image sequences of rapidly moving objects have to be acquired with high temporal resolution. If the standard video rate (30 frames/sec NTSC resp. 25 frames/sec CCIR) is not sufficient, high-speed solid state cameras may be considered offering frame rates of up to 15,000 frames per second. As the processing o...

Study of Magnetic Helicity Injection Via Plasma Imaging Using a High-Speed Digital Camera

The evolution of a plasma generated by a novel planar coaxial gun is photographed using a state-of-the-art digital camera, which captures eight timeresolved images per discharge. This experiment is designed to study the fundamental physics of magnetic helicity injection, which is an important issue in fusion plasma confinement as well as solar and astrophysical phenomena such as coronal mass ej...
