Abstract

For high speed frame recording the use of well-developed tomography methods of cross- section image reconstruction of 3-D objects is suggested in this paper. In case of changing one of spatial coordinates z to a time coordinate t an analogue of series of cross-section images, which are perpendicular to axis z, is a series of frames with various values of t. In this case projections needed for tomographic reconstruction can be realized as a set of streak records of 2-D images, obtained without a slit at various speeds of scanning. Digital simulation shows the possibility of reconstruction of the series of frames with temporal resolution approximating to that of streak recording. This paper also gives an example of chronotomographic reconstruction from projections, obtained in the model of chronotomograph.
