A kinematic fluorescence measurement band for use with a fluorescent light-emitting bead implanted within a user's body includes a band configured for secure and removable positioned about a portion of the user's body, a base plate configured for attachment to the band and an optical plate. The optical plate includes a rigid member with a light emitter and a light detector attached thereto. The light emitter of the optical plate is configured for emitting light that is absorbed by the fluorescent light-emitting bead while the light detector is configured for detecting fluorescent light emitted by the fluorescent light-emitting bead. In addition, the base plate and optical plate are configured for kinematic attachment, detachment and kinematic reattachment to one another via a cone-shaped indent, a slot-shaped indent, and a flat surface independently disposed on either of the base or optical plates in opposing relationship to first, second and third spherical components disposed on the other of the base or optical plates. |
