High-speed camera device

Figure 17.3 High-speed camera device used for dynamic observations of the weaving loom kinematics.

The first experiment was carried out without using the CH4-2 system. In the distance of 12 m from side A, plastic film was used to build an enclosed space, which was evenly filled with 45 m3 of mixed gas including CH4 and air. The high-speed camera was used to take photos of explosion phenomena in the exit of roadway and the system of collection and analyses was applied to analyse and record flame propagation speed passing by sensors when starting ignition device detonated mixed gas in the blind end. The experimental results were shown in Fig. 3 and Fig. 4. 

In the main there are two kinds of technologies for digital color cameras, the CCD (Charged Coupled Device) and the CMOS (Complementary Metal Oxide Semiconductor). While CCD cameras deliver images with a better quality and are more sensitive for low emittance, CMOS cameras are often used as high-speed cameras. Today, common CMOS high-speed cameras are able to record up to 32,000 images in a second. 

The architecture of the industrial high-speed cameras presented here and most other commercially available ones is similar in that the bandwidth of the image sensor is significantly higher than the bandwidth of the communicatiOT interface to a workstation PC. Therefore, these devices conduct three steps capture, store, and readout. This leads to two major drawbacks ... 

Many photographic products are based on the photolysis of silver halides. These materials are especially suitable for use where short exposure times are needed. Thus, high speed photographic films are manufactured for use in cameras. Also, coatings of silver halide on paper are utilized in the on-line production of colour reflection prints where rapid passage through an exposure device is necessary.

The detonation wave diffraction at the initiator/main detonation tube was observed using high-speed Schlieren and CH -chemiluminescence imaging which utilized a 10-nanometer FWHM interference filter centered at 430 nm and both DRS Hadland and Princeton Instruments intensified charge-coupled device (CCD) cameras.
