SYSTEMS AND METHODS FOR OPTICALLY MEASURING MUSCLE SARCOMERE LENGTH

摘要

Methods and systems for measuring muscle sarcomere length are disclosed. In an embodiment, a method comprises illuminating a set of muscle fibers with electromagnetic radiation, measuring an intensity of the electromagnetic radiation as reflected from the muscle fibers, the measuring occurring as a function of wavelength, determining wavelengths corresponding to maximums of reflected intensity, and correlating the determined wavelengths with respective muscle sarcomere lengths. In an embodiment, a system comprises an illumination source system for illuminating the set of muscle fibers with electromagnetic radiation, and an analyzer for measuring the intensity of the electromagnetic radiation as reflected from the muscle fibers.

1. A method of measuring muscle sarcomere length, comprising:
a. illuminating a set of muscle fibers with electromagnetic radiation; b. measuring an intensity of the electromagnetic radiation as reflected from the muscle fibers, the measuring occurring as a function of wavelength; c. determining one or more wavelengths corresponding to maximums of reflected intensity; and d. correlating the one or more determined wavelengths with an average muscle sarcomere length for the set of muscle fibers.
