| 摘要 |
This lens-free imaging system (20) comprises a receiving support (26) configured to receive a sample (24), a light source (30) configured to emit a light beam (50) for illuminating the sample (24) in an illumination direction (Z), the light source (30) comprising a diode (52) and a diaphragm (54), the diaphragm (54) being disposed between the diode (52) and the receiving support (26) in the illumination direction (Z), and a matricial photodetector (32) configured to acquire at least one image of the sample (24), each image being formed by radiation emitted by the illuminated sample (24) and comprising at least one elementary diffraction pattern, the receiving support (26) being disposed between the light source (30) and the photodetector matrix (32) in the illumination direction (Z). The system (20) further comprises a light diffuser (56) disposed between the diode (52) and the diaphragm (54). |
