Frequency Based Measurement of Characteristics of a Substance

摘要

In a downhole environment, utilizing one or more ICE modules, in response to detecting light by one or more channels of a light to voltage converter, the detected light is converted into one or more voltages. The light has previously interacted with a downhole substance and has been processed by an integrated computational element. The one or more voltages are converted into one or more analog frequencies. The one or more analog frequencies are converted into one or more digital frequencies. One or more intensities are determined from one or more digital frequencies. One or more components of the substance are determined in response to the determined one or more intensities.
