Abstract

Cette invention a trait à un nouveau microscope ainsi qu'à une méthode d'obtention d'images associant la technique classique d'éclairage à fond sombre à une inversion d'image électronique (conversion d'une image positive en image négative) et s'appuyant sur d'autres améliorations pour renforcer le contraste et augmenter la résolution de l'image finale. On estime que ce microscope et la méthode afférente, dénommés dans le cadre de cette invention contraste fond noir inversé (IDC), conviendront particulièrement à l'examen de cellules vivantes en temps réel et ce, sans coloration ou préparation quelconques.
