Abstract
A method is provided for observing a biological sample between a light source and a pixelated image sensor, the light emitting an incident light beam, which propagates to the sample along a propagation axis and at an emission wavelength, the method including: illuminating the sample with the source; and acquiring an image of the sample with the sensor, no image-forming optic being placed between the sample and the sensor, the sample absorbing some of the beam, such that the acquired image is representative of an absorption of the beam by the sample at the emission wavelength, the source illuminates an area of the sample larger than 1 mm, the image acquired of the sample by the sensor corresponds to an area of sample larger than 1 mm, and pixels of the sensor define a detection plane, the sample being placed at a distance from the plane smaller than 1 mm.
