An optical scanner includes a light source, an optical phased array, a monitoring light receiving unit, and a signal processing unit. The optical phased array implements scanning by a light beam by individually controlling phases of a plurality of branched lights into which light supplied from the light source is branched, using a scanning phase amount, and radiating light from an antenna array that has a plurality of antenna elements. The monitoring light receiving unit receives light radiated from the optical phased array. The signal processing unit detects characteristics of the light beam from a detection result of the monitoring light receiving unit and generate a phase adjustment amount for correcting the scanning phase amount such that a detection value of the characteristics coincides with a design value prepared in advance.

An optical scanner includes a light receiving unit, a reference light irradiating unit, and a light-receiving-side correcting unit. The light receiving unit includes an optical phased array that implements scanning by a light beam by individually controlling phases of a plurality of branched lights using a scanning phase amount.

The present invention relates to a method for detecting changes in the ore grade of a rock face in near real time. The method includes the step of providing a scanning system having at least a hyperspectral imager, a position system, a LiDAR or range determination unit and computational resources. Further, the method involves determining a precise location of the scanning system utilising the position system. The rock face is scanned with the range determination unit to determine rock face position information. The method involves scanning the rock face with the hyperspectral imager to produce a corresponding rock face hyperspectral image. Further the method involves utilising the computational resources to fuse together the rock face position information and the corresponding rock face hyperspectral image to produce a rock face position and content information map of the rock face.
