Abstract
An optical detection apparatus is arranged to detect particles in a fluid flowing through a tubing portion of transparent or translucent material. The apparatus comprises a holder for the tubing portion; a light emitting device configured to irradiate a target volume inside the tubing portion when arranged in the holder; and at least one light receiving device configured to receive light from the target volume when irradiated by the light emitting device and generate one or more time-dependent output signals indicative of the received light. A computation device is configured to determine a parameter indicative of temporal variability in the one or more time-dependent output signals and estimate the density based on the parameter, which has been found to be robust to structural differences between tubings and allows the apparatus to be deployed without calibration.
