The key techniques of GD 96 type electrical control device for high speed camera were introduced in this paper. The device was used to control GS 96 type high speed camera and XGS 3 type high speed camera.
On this condition, the main features of WJJ-16mm minitype High speed camera which has been successfully developed are as follows: the maximum photographic rate 200f/s, the photographic resolving power> 50 lp/mm, the picture steadiness σy, < 0.01mm (temporal direction) and σc≤0.012mm (spacial direction), and the recorded information related to time in each frame by means of close-touch imaging through the integrated LED unit.
Using of a coaxal shutter system, the camera has a rather simple structure, lighter wieght and smaller dimension than other 35mm high speed cameras. The weight of the camera is less than 8kg and 1/5- 1/10 of other cameras with same type.
Stress waves propagation in the solid such as reflection, interference and diffraction was observed using polarized optics and an Imacon high speed camera (operating at both of 106 and 5×105 framing rates per second, fps).
The changes of the contraction amplitude in comparsion to the basal cell shortening (cell shortening in μm and %) were continuously recorded with a one-dimensional high speed camera.
Essential of this method is an image derotator combined with a high speed camera or a laser doppler vibrometer (LDV).
The shape of the bubble is observed simultaneously with a second high speed camera.
The time histories of water droplets were recorded by using a high speed camera.
The evidence accumulated so far implies that small telescopes equipped with high speed cameras can be used as a new tool for studying meteoroid streams, sporadic meteoroids, and hypervelocity collisions.
Flow visualization is accomplished using the same high speed cameras used in the 1 g ground experiments.
It was digitized from the early frames captured by one of six high speed cameras employed in this highly instrumented test.
In the present study four progressive scan cameras were used; however, the technique works also with standard CCD or even high speed cameras.
The velocity profile is estimated in the lower part using an image analysis device from two high speed cameras.
