Abstract:
It has been found practical to take a nearly continuous set of light scattering photographs from a single sample by using a continuous wave C. W. gas laser as the source, and a high speed motion picture camera as the detector. The polarized beam from a Spectra Physics Model 130 C.W. Laser was passed through a suitable cutoff filter to eliminate the blue fluorescent light, and then through a pin hole. The sample was placed in the rapid stretching device described previously AAD-420 270. A polaroid sheet analyzer was placed between the sample and the photographic film. Generally, no lens was used in the Fastax WF-17 or other movie cameras employed. With a Fastax WF-17 Camera and a Spectra Physics Model 115 Gas Laser as source, good scattering patterns were obtained at camera speeds as high as 5400 frames per second, using Kodak Tri-X Negative film. There was change in HV scattering patterns on stretching medium density polyethylene, using a camera of intermediate speed.
