High-throughput characterisation of bull semen motility using differential dynamic microscopy
Fig 5
Measured g(q, τ) from a movie (10×, 100 fps, 500 p, 200 s) of an in-active sample at q = 2.22μm−1 with a cell density of ≈ 20 × 16cells/ml.
Line is a fit using two exponential functions returning two separate diffusion coefficient D1 and D2. Right inset: fitted parameters D1 and D2 for a range of q. Left inset: Fitted measurement of the fractional contribution, γ, of the debris to the total signal.
