“…An earlier version, based on the commercially available monochrome high-speed camera HPV-1 built by Shimadzu, had already been applied in another preliminary set of tests which achieved the first MHz-range timeresolved color schlieren visualization of shock wave phenomena [10]. The main difference between the new prototype and the older one described in [5] is the considerably higher resolution (300 000 pixels as opposed to 80 000) and the larger number of frames (144 vs. 100) [3], [4]. Both instruments have in common an In-Situ Storage Image Sensor (ISIS) CCD chip [3], [4], [10] which allows one to achieve frame rates in the MHz range without sacrificing image resolution.…”

The latter aspect is the main difference between these cameras and other commercially available high-speed video systems except for the (monochrome) Shimadzu HPV-1, which is also based on the ISIS sensor technology.…”

“…Thus the requirement for a continuation of the investigation was to find a camera that could take highresolution color images at higher frame rates. This eventually became possible by using a newly developed high-speed color video system, which could record 144 frames at full-frame resolution with frame rates up to 1 000 000 fps [3], [4].…”

In order to investigate the unsteady flow field around a spiked body in supersonic flow, time-resolved color schlieren visualization was applied using a high-speed video camera which could take up to 1 000 000 frames per second at full frame resolution. Conically and spherically tipped spikes of six different lengths could be attached at the center of the model and their effect on the flow unsteadiness was visually observed. The obtained images revealed in great detail the interaction between the incoming free stream flow and the high-pressure region near the model base, which could make its presence known upstream at the tip of the spike by means of displacing the boundary layer on the spike and subsequently inducing a large-scale instability of the flow.

“…After the termination of the image-capturing operation, the image signals for 144 frames in the linear CCD storages are read out from the 300,000-pixel ultrahighspeed CCD. The main characteristics of the 300,000-pixel ultrahigh-speed CCD are listed in Table 1 4,5) . The frame rate, which depends on the transfer rate of the linear CCD storage, is up to 1,000,000 fps.…”

An ultrahigh-speed color video camera operating at 1,000,000 fps with 288 frame memories

We developed an ultrahigh-speed color video camera that operates at 1,000,000 fps (frames per second) and has the capacity to store 288 frame memories. The camera utilizes a beam splitter and two ultrahigh-speed 300,000-pixel CCDs (Charge Coupled Device), each having 144 frame memories. Each CCD is located at each of the two outputs of the beam splitter. The CCD driving block was developed to separately drive two CCDs, so that the recording period of the two CCDs is sequentially switched. This enabled the capture of 288 frames, an increase of a factor of 2 over that captured by our conventional ultrahigh-speed camera. A microlens array for the ultrahigh-speed CCDs was also developed to improve the light sensitivity. We fabricated a down-facing, cylindrical microlens array on the glass substrate using resinstamping technology. The microlens array increased the light sensitivity of the CCD by 2.2 times at the F-number 1.4. Using the beam splitter in conjunction with the microlens array, the ultrahigh-speed color video camera which enables to capture 288-frame images without decreasing the camera's light sensitivity has been successfully developed.
