1. A system for measuring an angle of repose of granular material, comprising:
a hollow chamber having at least one sidewall with an optically transparent window mounted therein;
a cylindrical receptacle rotatably mounted within the hollow chamber, wherein the cylindrical receptacle has opposed open and closed ends, the open end thereof being releasably covered by an optically transparent plate, the cylindrical receptacle being adapted for receiving a volume of granular material and the cylindrical receptacle being oriented with respect to the hollow chamber such that the optically transparent plate faces and is aligned with the optically transparent window;
means for selectively rotating the cylindrical receptacle within the hollow chamber;
means for selectively adjusting a temperature within the hollow chamber; and
a camera for detecting an angle of repose of the granular material when the cylindrical receptacle is rotated within the hollow chamber, the camera being positioned external to the hollow chamber such that the granular material may be viewed by the camera through the optically transparent plate and the optically transparent window.
