METHOD AND SYSTEM FOR OBSERVING A SAMPLE UNDER AMBIENT LIGHTING

A method for observing a sample is placed between a light source and an image sensor, comprising at least 10000 pixels, the light source emits an illuminating beam, which propagates to the sample, the light beam is emitted in an illumination spectral band (Δλ11) lying above 800 nm, the method compri...

Zusammenfassung:A method for observing a sample is placed between a light source and an image sensor, comprising at least 10000 pixels, the light source emits an illuminating beam, which propagates to the sample, the light beam is emitted in an illumination spectral band (Δλ11) lying above 800 nm, the method comprising the following steps: (a) illuminating the sample with the light source; (b) acquiring an image of the sample (I0) with the image sensor, no image-forming optics being placed between the sample and the image sensor; and (c) the image sensor being configured such that it has a detection spectral band (Δλ20), which blocks wavelengths in the visible spectral band, such that the image may be acquired in ambient light.
