Abstract
(EN)
Methods and apparatus are provided for determining a characteristic of a sample of a material by the interaction of electromagnetic radiation with the sample. The apparatus includes an optical assembly and a protective barrier. The optical assembly sequentially illuminates a plurality of volume elements in the sample with an intensity distribution in the sample that drops off substantially monotonically from a first region in a first optical path and collects electromagnetic radiation emanating from each of the volume elements. The optical assembly collects the electromagnetic radiation emanating from each of the volume elements with a collected distribution that drops off substantially monotonically from a second region in a second optical path. The first and second regions at least partially overlap in each of the volume elements. The optical assembly can be configured as a probe, to be directed to the evaluation of a sample of a biological material. A protective barrier can be disposed between the optical assembly and a body tissue, to prevent contamination of the optical assembly by said body tissue.

L'invention concerne un dispositif et des procédés servant à déterminer une caractéristique d'un échantillon d'un matériau, par interaction d'un rayonnement électromagnétique avec l'échantillon. Ce dispositif comprend un ensemble optique et un écran protecteur. L'ensemble optique éclaire de manière séquentielle plusieurs éléments de volume de l'échantillon à l'aide d'une répartition de l'intensité, dans l'échantillon, qui chute de manière sensiblement monotone à partir d'une première région située dans un premier trajet optique, et reçoit le rayonnement électromagnétique émanant de chaque élément de volume. L'ensemble optique reçoit le rayonnement électromagnétique émanant de chaque élément de volume, avec une répartition reçue qui chute de manière sensiblement monotone à partir d'une seconde région située dans un second trajet optique. Les première et seconde régions se chevauchent l'une l'autre, au moins partiellement dans chaque élément de volume. L'ensemble optique peut être conçu comme une sonde à diriger pour évaluer un échantillon d'un matériau biologique. Un écran protecteur peut être placé entre l'ensemble optique et un tissu corporel, afin d'empêcher la contamination de l'ensemble optique par le tissu corporel.
