Optical data transformation
First Claim
1. An apparatus, comprising:
- a housing having a cavity and attachable adjacent to an external surface of a down hole pipe having an internal fluid-flow region;
an optical calculation device located at least partially within the housing cavity, the optical calculation device including;
a light source;
an internal reflectance element configured to receive light from the light source and allow the light to interact with a fluid in the internal fluid-flow region to produce interacted energy; and
at least one multivariate optical element to receive the interacted energy and to optically compress data carried by the interacted energy into at least one orthogonal component;
a detector to generate an electrical intensity output signal responsive to the at least one orthogonal component, the signal associated with a value corresponding to a property of the fluid in the internal fluid-flow region; and
a wire or telemetry apparatus to transmit the signal to a remote surface computer.

Abstract
Apparatus, systems, and methods may operate to receive interacted energy at an optical calculation device attached to a down hole housing to be deployed in a down hole environment. Further activities may include optically compressing data carried by the interacted energy into at least one orthogonal component, using the optical calculation device, sending a signal associated with the at least one orthogonal component to a remote surface computer, and determining a property of petroleum located in the down hole environment using the remote surface computer, based on the signal. The optical calculation device may comprise a multivariate optical element (MOE). Additional apparatus, systems, and methods are disclosed.
