Abstract : Several designs of photoelectric plethysmographs utilizing fiber optics are described. One arrangement is used for studies on the cutaneous circulation. A modification of this design was applied successfully to the oral mucosa in climate chamber experiments. With a light wire substituted for the photocell, interference filters and multiplier phototubes may be combined for spectrophotometric recording. This arrangement is particulary useful for following changes in blood content of the illuminated tissue during changes in ambient temperature. (Author)
