Systems and methods related to optical measurement of vibrations experienced by components may include a light source, a reflector associated with a component to be measured, and an optical sensor. In addition, the systems may include one or more fiber optic cables to transmit emitted light between the light source and the reflector, and to transmit reflected light between the reflector and the optical sensor. The optical measurement systems may enable detection of a large dynamic range of vibrations experienced by components or systems, and may also enable determinations related to high cycle fatigue and other stresses. Further, the optical measurement systems may be integrated into systems having various components to be measured, thereby enabling continuous, in-situ measurement of vibrations and health, as well as continuous monitoring and adjustment of operations of such systems.
