19 Claims

1. Device for holographic and hyperspectral measuring and analyzing of a sample, wherein said device comprises:

an acquisition device of an image containing spectral and amplitude information of the light signal illuminating said sample; and holographic interference figures of a reference light beam and of a light beam having illuminated said sample containing the amplitude and phase information of the light signal illuminating said sample; and

an illumination device of said sample; and

a device for reconstructing the hyperspectral holographic image and analyzing the amplitude, phase and spectrum properties of the light illuminating said sample integrating a deep and convolutional neural network architectured for calculating a probability of presence of the particularity sought in said sample from the hyperspectral holographic image, and generating an image for each sought particularity whose value of each pixel at the x and y coordinates corresponds to the probability presence of said particularity at the same x and y coordinates of said sample.
