title: A scanning light diffractometer for muscle studies.
abstract: A light diffractometer with a cosecant drive is described. It can provide the intensity spectrum of the fine structures within the first-order laser light diffraction from striated muscle. In addition, the sarcomere length associated with each fine structure can be obtained. The accuracy of the sarcomere length determination is discussed.
