(left) Schematic diagram of the incoherent lensfree holographic microscope that is used for imaging of C. elegans samples on a chip. A pinhole with a diameter of D (50–100 μm) is illuminated with a spatially incoherent light source. z1 (5–10 cm) and z2 (~1 mm) are the aperture to sample and sample to sensor distances, respectively, where z1 >> z2. (right) A monochrome CMOS sensor array with a pixel size of 2.2 μm was used for recording lensless holograms presented in this paper.
