[en] A pulse motor has been developed which enables a mirror to be rotated to speeds in excess of 20,000 rpm with 10^-4s. High-speed cameras of both streak and framing type have been assembled which incorporate this mirror drive, giving streak writing speeds up to 2,000ms^-1, and framing speeds up to 500,000 frames s^-1, in each case with the capability of triggering the camera from the event under investigation.

[en] Optical engineering at Los Alamos, which began in 1943, has continued because scientific researchers usually want more resolving power than commercially available optical instruments provide. In addition, in-house engineering is often advantageous - when the technology for designing and making improved instrumentation is available locally - because of our remote location and the frequent need for accurate data. As a consequence, a number of improved research cameras and lens systems have been developed locally - especially for explosion and implosion photography, but even for oscilloscope photography. The development of high-speed cameras led to the ultimate in practical high-speed rotating mirrors and to the invention of a rapid, precise, and effective lens design procedure that has produced more than a hundred lens system that gives improved imaging in special conditions of use. Representative examples of this work are described

[en] The reality is analysed of the Perseus Flasher (PF), which was found as a source emitting frequent and short optical flashes. Plates from the Ondrejov Observatory plate collection were processed. No confirmation was found on time-correlated plates for 4 events and on plates representing a total of 1350 hours of exposure. It was shown that the conclusions drawn by Katz et al. (Astrophys. J. Let. 307, L33) were must erroneous and that the object was of nonastrophysical origin. The reported PF frequency is considerably higher than the estimated frequency of background flashes, and difficulties exist in the interpretation of the PF as a satellite glints phenomenon. Another plausible explanation is suggested, namely that a large part (>50%) of the optical flashes reported as PF are of physiological origin. (author). 3 tabs., 13 refs

[en] The 10-ps streak camera has been redesigned to simplify its operation, reduce manufacturing costs, and improve its appearance. The electronics have been simplified, a film indexer added, and a contacted slit has been evaluated. Data support a 10-ps resolution. (author)

[en] It is intended to present some general considerations about ''Higg-speed photography'' as a tool of work common in mos research laboratories in the world. ''High-speed photography'' relies on the principles of photography of actions, that change rapidly with the time. The evolution of this technique goes along with the discovering of new phenomena in wich higher speeds are involved. At present is normal to deal with changing rates involving picoseconds times (10^-12 s) and new developments on the field of femtosecond (10^-15 s) theoretically are contemplated. (author)

[en] The dissector--restorer framing tube developed by our Electrical Engineering Department will aid scientists studying phenomena in very fast plasma experiments. This new framing tube dissects a continuous image and restores the dissected portion as a framed image. Our prototype forms three framed images in series, each with a frame period of about 100 ps. A photocathode version is now under construction for use in the laser fusion program to study laser-generated plasmas

[en] A new camera is described with slit scanning and very high photonic gain (G=5000). Development of the technology of tubes and microchannel plates has enabled integration of such an amplifying element in an image converter tube which does away with the couplings and the intermediary electron-photon-electron conversions of the classical converter systems having external amplification. It is thus possible to obtain equal or superior performance while retaining considerable gain for the camera, great compactness, great flexibility in use, and easy handling. (author)
