CONTINUOUS-WRITING STREAK CAMERA FOR DIFFRACTION STUDIES.
Abstract
This report describes a high speed, continuous-writing, streak camera developed for recording time-dependent optical diffraction phenomena. The elements of the camera include an initial optical relay system, a continuous-streaking system based on a rotating optical polygon, and terminal optics in the form of a conventional camera with rectangular format that permits Polaroid use. Developed primarily for use with diffraction grating strain gages in dynamic situations where events cannot be triggered reliably with respect to time, the camera system may be of use in other situations where a continuous-writing streak capability is needed. The repetitive sweep time is variable to a minimum of 500 microsec and additional change in writing rate may be achieved easily by changing the terminal lens system. (Author)
