SYSTEM AND METHOD FOR DETERMINING FLUID PARAMETERS

摘要

A system and method for measuring the quality of a fluid includes an optical body (18) forming a measurement surface (14) configured for contacting the fluid (20) to be measured; a light source (12) for projecting radiant energy (15) into the optical body (18) and toward the measurement surface (14) at a predetermined angle; an optical sensor module (16) arranged for detecting an image of at least reflected radiant energy (24) from the measurement surface (14), the optical sensor module (16) includes a two-dimensional array of light sensors or pixels, each pixel having a plurality of brightness levels; and a processor (54) for setting a brightness threshold value, comparing the threshold value to the brightness level of each pixel, and counting the number of pixels above and/or below the brightness threshold value.
