A method for determining the position &#x3b8; of a moving part (T) along an axis (X), using an inductive sensor () including: a primary winding (B) generating an electromagnetic field; a first secondary winding (R), generating a first voltage signal (V), of the sine function type; a second secondary winding (R), generating a second voltage signal (V) of the cosine function type; and a calculation unit ('), wherein the method includes the steps of calculating and distributing linearization points i on the arctangent function tan(&#x3b8;) resulting from the ratio of the first voltage signal to the second voltage signal, the linearization points i being distributed according to a sinusoidal function in order to reduce the error on the position (&#x3b8;) of the target (T) at the ends (E, E) of the primary and secondary windings (R, R).

An inductive sensor () for a motor vehicle, includes:

Inductive sensor for a motor vehicle, comprising electric oscillators designed to form an AC voltage at the terminals of a field coil by means of electric resonance

A device for measuring a spectrum of a light beam, in a wavelength range chosen beforehand, the spectrum being generated by a sample to be analyzed, the optical measuring device including at least one light source, a measurement cell and a measurement detector placed on a measurement optical pathway, the measurement optical pathway being taken by a measurement optical beam emitted by the light source, and encountering the measurement cell, a self-calibration unit allowing any drift of the light sources, due to environmental conditions or conditions of use, to be taken into account independently of whether a sample to be analyzed is present in or absent from the measurement cell, the self-calibration unit including elements for creating a reference optical pathway, taken by a reference optical beam emitted by the light source, and not encountering the measurement cell, and a reference detector.
