1. A method, comprising:

  • directing light to interact with a dynamic and moving stream of fluid, including crude petroleum flowing in a stream, as part of first and second measurement procedures, and causing the fluid to produce interacted light from the directed light associated with each of the measurement procedures;

    dividing the interacted light associated with each of the measurement procedures into reflected light and transmitted light, the reflected and transmitted light each having an intensity;

    producing first and second signals, respectively based on the intensity of the transmitted and reflected light associated with the first measurement procedure, and producing third and fourth signals, respectively based on the intensity of the transmitted and reflected light associated with the second measurement procedure; and

    determining at least two different properties of the dynamic and moving stream of fluid based on the first, second, third, and fourth signals, including determining properties of the crude petroleum flowing in the stream in a down hole environment,wherein the causing, dividing, and producing steps are performed in situ at the stream.
