Abstract
Provided is a water examination device including: a main body; a cup accommodation unit formed inward from a surface of the main body such that a cup containing a fluid is accommodated therein; a wave source for irradiating a wave toward the cup accommodation unit; a detector for detecting a laser speckle generated by multiple scattering of the irradiated wave in the fluid, at every time point set in advance; and a controller for estimating whether foreign substances exist in the fluid in real-time by using the detected laser speckle.
Claims11
A water examination device comprising:
- a main body;
- a cup accommodation unit formed inward from a surface of the main body, and wherein the cup accommodation unit is adapted to receive a cup containing fluid;
- a wave source for irradiating a wave toward the cup accommodation unit;
- a detector for detecting a laser speckle generated by multiple scattering of the irradiated wave in the fluid, in time-serial manner;
- and
- a controller for estimating whether foreign substances exist in the fluid in real-time by using the detected laser speckle,
- wherein the cup accommodation unit comprises:
- a bottom portion formed in the main body;
- and
- a wall portion extending from the bottom portion toward the surface of the main body, wherein the bottom portion and the wall portion form a receiving region that is adapted to receive the cup, and wherein the wall portion is formed to have an annular shape and is formed to be narrowed toward an upper portion of the main body;
- and
- wherein an angle between the bottom portion and the wall portion is not a right angle.
A water examination method comprising:
- inserting, into a cup accommodation unit, a cup in which a fluid is capable of being accommodated;
- irradiating, by a wave source, a wave having coherence to the cup accommodation unit, in which the cup is accommodated;
- detecting, by a detector, a laser speckle generated by multiple scattering of the irradiated wave from the wave source in the fluid, in time-serial manner;
- and
- estimating, by a controller, whether microorganisms exist in the fluid in real-time by using the detected laser speckle, and
- wherein the cup accommodation unit comprises:
- a bottom portion formed in the main body;
- and
- a wall portion extending from the bottom portion toward the surface of the main body and formed to surround at least a part of a side surface of a cup accommodated in the cup accommodation unit, wherein the wall portion is formed to have an annular shape and is formed to be narrowed toward an upper portion of the main body;
- and
- wherein an angle between the bottom portion and the wall portion is not a right angle.
