Incoherent lensfree on-chip imaging of two different C. elegans samples. (a1 and b1) Raw lensless holograms captured by the sensorarray. (a2 and b2) Intensity images of the reconstructed holograms using method 1. (a3 and b3) Intensity images of the reconstructed holograms using method 2. (a4 and b4) Conventional 10× (NA = 0.2) transmission microscope images of the same samples for comparison. The bottom two rows show the zoomed-in images to better illustrate the comparison. Experimental parameters: z1 = 10 cm, z2 = 1 mm, D = 50 μm, spatially incoherent light source at λ = 500 nm with a bandwidth of ~15 nm. Exposure time ≈ 30 ms.
