Kamax patented technology combines two elements :
a system of scanning based on the polarimetry that permits real time view of the cancerous tissues and an offset through endoscopic optical fiber which could be transferred by a beam catheter in the areas difficult to access.
The practitioner’s diagnosis is thus more precise, more complete, and more rapid.

What is Polarimetry ?

Light is an electromagnetic ray in the same way as the electromagnetic waves or the X ray. It carries the energy keeping in parallel all the properties of a wave, that is, disruption and a propagating vibration. In the case of a ray of light, the oscillating scales are those of the electrical and magnetic fields the association of which being called the electromagnetic field. These two scales oscillate at a very high frequency, in a perpendicular shape in the direction of their propagation, like the wave created on the surface of a calm stretch of water when we throw a stone: It is possible to state that the light wave is a transversal wave. The electric field, whose scale can be measured by a detector, can be constantly represented by an arrow (called “electrical field carrier”) the length and the direction of which indicates respectively the immediate equivalent of the field, its direction as well as its orientation. The path of the M extremity of this electrical field carrier in the oscillating form manifests the polarization of light. Thus, if this path remains straight, that is, if the direction of the field remains unchanged in the course of time, it is referred to as the rectilinear polarization. In the same way, the circular paths or the elliptical ones will be the characteristic of the circular or the elliptical polarizations. In certain cases, one can observe more or less considerable amounts of unpredictable fluctuations around a perfect (rectilinear, circular or elliptical) path indicating that the associated light wave is more or less depolarized. A partially depolarized light is characterized by its rate of depolarization. As a light beam interacts in a certain environment called “sample”, it is possible to observe a modification in the state of polarization between the incident beam and the transmitted or the reflective one. The nature and the size of this modification, for example the transformation of a rectilinear polarization into an elliptical one or a modification in the rate of depolarization, conveys microscopic structuring scales in the sample. The technique of substantial analysis (characterization) to enlighten a sample with a known polarization and to analyze the state of the returned polarization is called the polarimetry.
