A gold detection apparatus capable of detecting gold in field mineral samples such as rock or soil with little or no preparation. Light in red, green and violet wavelengths is directed at a surface of a mineral sample and the reflected light intensity is measured by an array of sensors or photosites. Based on the characteristic reflectance properties of gold, the reflected light intensity in each wavelength is used to determine the presence of gold particles and the gold concentration of the mineral sample.

Method and apparatus for gold detection

A motion system or goniometer for moving a sample supported by the system has a triangular plate supported at each apex by actuators that can extend or retract axially independently from one another. The actuators are mounted on x-y translation stages and a .theta. rotation stage. The movement of the actuators, translation stages and rotation stage is controlled by a computer. When it is desired to create a rocking curve at a particular position on the sample, the translation stages and rotation stage can remain stationary while moving only the plate and actuators. The goniometer is much more efficient and less expensive than previous devices which require movement of the entire goniometer when creating a rocking curve.
