a
Standard deviation values of both the theoretical and experimental results are evaluated with the lensfree holograms of Figs. 3 (a), (b), and (c).
b
The theoretical standard deviation (STD) in height of each micro-particle type is evaluated by summing the height deviation contributed by detection noise, pixelation error, and bead size deviation.
