GEOMETRIC SPATIAL AND TEMPORAL MODELIZATI ON OF A STREAK CAMERA

This article deals with the elaboration of a geometric spatial and tem poral model of a streak camera. This camera is used as a chronometer i n the detonating experiments. To calculate the spatial and temporal ge ometric model, it is necessary to establish the axis of the plane face of the camera with axis recorded on a film. To achieve this, we use R LS algorithm with forgetting factor. The determination of parameters o f model will allow to improve the accuracy of chronometric measures wh ich we have carried Out, by permitting a temporal steady of performanc es of streak cameras to detect possible defects during the experiment.
