摘要： Methods and apparatus to optically determine velocities of downhole fluids are disclosed. Some example methods to determine a velocity of a downhole fluid include exciting a fluorescent substance in a downhole fluid with an optical signal via an optical interface. The example methods further include detecting fluorescence of the downhole fluid via an optical fiber at a predetermined distance from the optical interface, and determining the velocity of the downhole fluid based on the detected fluorescence.
