Okla. Stat. tit. 59, § 59-1452: Purpose

It is the purpose of this act to regulate all persons who

purport to be able to detect deception or to verify truth of

statements through the use of instrumentation (as lie detectors,

polygraphs, deceptographs, and/or similar or related devices and

instruments without regard to the nomenclature applied thereto) and

this act shall be liberally construed to regulate all such persons

and instruments. No person who purports to be able to detect

deception or to verify truth of statements through instrumentation

shall be held exempt from the provisions of this act because of the

terminology which he may use to refer to himself, to his instrument,

or to his services.
