Device for the high-speed photography of an object.

摘要

The device for the high-speed photography of an object (1) consists of a source (2) of laser light illuminating the object, a photosensitive film (3) and a high-speed deflector (5) placed between the object and the film. The deflector is designed to make the image of the object sweep along a line on the film. A Pockels cell (4) is placed in the optical path between the object (1) and the high-speed deflector (5). The Pockels cell can be controlled by a sequence of electrical pulses during each sweep cycle of the high-speed deflector so that a set of distinct images of the object are sent towards the deflector. The device can be applied particularly to the optical analysis of high-speed phenomena. <IMAGE>
