Abstract: An optical system suitable for determining a characteristic as a function of time of at least a part of a liquid volume comprising a plurality of objects. The optical system provides a fast detection of a change in the liquid volume. The optical system comprises - an optical detection assembly comprising at least one image acquisition device configured to acquire images of an image acquisition area; - a sample device comprising at least one sample container suitable for holding a sample of said liquid volume; - a translating arrangement configured to translate said image acquisition area through at least one part of said sample container to perform a scan along a scanning path through said part of said sample container; and - an image analyzing processing system. The optical system is programmed to perform consecutive scans through said at least one part of said sample container, wherein each scan comprises acquiring images at a plurality of image acquiring positions of the image acquisition area by the optical detection assembly along at least one scanning path of the scan. The image analyzing processing system is programmed to determine a set of features in the form of a set of values for each of a plurality of objects captured on said images from each respective scan and to determine for each scan at least one derived result, the derived result is derived from a plurality of the sets of values, and to present said derived result obtained from the respective, consecutive scans as a function of time.
