Quantitative liquid texture measurement apparatus and method
First Claim
1. An apparatus for quantitative texture attribute measurement of a liquid, the apparatus comprising:
- a housing;
a laser generator attached to the housing;
an acoustic capturing device proximally located to the housing;
a data processing unit in communication with at least the acoustic capturing device;
wherein a laser from the laser generator is directed to strike the liquid to create an arc impacting a surface of the container, and thereby producing an acoustic signal from vibration of the impacted surface of the container to be detected by the acoustic capturing device;
wherein the data processing unit is configured to quantitatively measure the texture attribute of the liquid based on input from the acoustic capturing device generated based on said detected acoustic signal.

Abstract
A photo acoustic non-destructive measurement apparatus and method for quantitatively measuring texture of a liquid. The apparatus includes a laser generating tool, an acoustic capturing device, and a data processing unit. The laser generating tool directs a laser towards a surface of a liquid contained in a container and creates pressure waves that propagate through the air and produce an acoustic signal. The acoustic capturing device records and forwards the signal to a data processing unit. The data processing unit further comprises a digital signal processing module that processes the received acoustic signal. A statistical processing module further filters the acoustic signal from the data processing unit and generates a quantitative acoustic model for texture attributes such as hardness and fracturability. The quantitative model is correlated with a qualitative texture measurement from a descriptive expert panel. Textures of liquids are quantitatively measured with the quantitative acoustic model.
