Abstract: A measuring arrangement (101) comprises an illuminating arrangement (110) to emit coherent light (111);a cuvette (120) defining an inner volume (121)for receiving a fluid (130) possibly comprising microscopic objects (140) of foreign origin, the cuvette being arranged to receive the coherent light and let it exit therefrom through opposite entrance and exit openings(150, 153), the entrance opening (150) being closed by an entrance window (151), whereby the possible microscopic objects present in the fluid scatter part of the light, the scattered and non-scattered light interfering to form interference fringes; an image sensor (160), the image sensor being configured to capture a hologram digital image frame (170) by receiving the light propagated across the cuvette; and an exit window (152) arranged to close the exit opening (153) of the cuvette. The image sensor (160) is mounted in direct contact with the cuvette(120).
