Instant-image camera

In 1978, Kodak were the first to introduce the multilayer film technique to the laboratory of the clinical pathologist and clinical chemist. This innovation had been decisively promoted by the development of the instant-image camera for space travel. 

Layers can be photographed in black and white or color under daylight or UV light with appropriate filters. Commercial TLC camera stands are available for use with Polaroid instant image or 35 mm cameras. For optimal photographic reproduction of a TLC plate or sheet, both reflected (45°) and transmitted light and a combination of these should be available and tested. Workers familiar with... 

Polaroid introduced Polavision, a Super-8-mm instant motion picture system, in 1977 (97). Polachrome CS 35-mm sHde film followed in 1982 (98), and a high contrast version, Polachrome HCP, appeared in 1987. Each of the films comprises a very fine additive color screen and an integral silver image transfer film. The Polavision system, which included a movie camera and a player that processed the exposed film and projected the movie, is no longer on the market. The Polavision film was provided in a sealed cassette, and the film was exposed, processed, viewed, and rewound for further viewing without leaving the cassette (97). 

N)lntermittent Film Movement Camera., A camera in which it is possible to record a rapid succession of images by arresting the film movement at the instant when exposure is desired, may be so called. Shutter mechanisms allow individual picture-exposure times to be varied over a ratio ca 20 1 (Ref 18,p 13)... 

Temperature measurement by two-dye fluorescence requires efficient separation of the two fluorescent emissions so that their emissions can be imaged separately over identical spatial domains at the same instant in time. Such separation is achieved by adding a second camera and additional spectral filters to the aforementioned single-dye optical arrangement (these additions are identified by the dashed bounding box in Fig. 2). In this optical arrangement, both dyes... 

To obtain information about the velocity of the process being viewed the camera film should move perpendicularly to the direction of the process propagation, i.e., to the light emission propagation direction. Thus, the image of the process, which is projected on the film by the objective lens, is transformed into a laterally moved luminous trace from which the distance-time curve is obtained. By additional treatment of the distance-time curve, the velocity of the process at any instant of its propagation may be calculated applying an appropriate numerical procedure. 

The bubble behavior was observed with a high-speed video camera at 200 frames per second. The images were recorded on a personal computer and then processed to determine the shape and size of the bubble at every instant. The horizontal and vertical sizes of the bubble before collision with the plate were denoted by d y and...
