(a) Experimental set-up with digital in-line holographic microscopy. (b) Coordinate system used for calculating the local concentrations of the microparticles. (c) Typical holographic image of erythrocytes with subtracted background image. (d) Reconstructed holographic images of an erythrocyte in the yellow square box of (c) at (i) z = −3 μm and (ii) z = 20 μm with a TC profile. (e) In-plane positions of detected erythrocytes. (f) 3D spatial distribution of 3000 erythrocytes in the microchannel. Scale bars are 10 μm.
