1. A laser osteotomy system for shaping hard biological tissue including bone, the system comprising:
a tool comprising a laser operable to perform at least one action of work comprising laser ablation;
positioning means for positioning the tool relative to the hard biological tissue to perform the at least one action of work;
an input means;
an optical sensor operable to measure light interaction with the hard biological tissue and an environment around the hard biological tissue; and
a controller to:
receive input via the input means, the input comprising but not limited to the light waves measured by the optical sensor,
perform processing on the input for mapping and identification of the hard biological tissue and an environment around the hard biological tissue,
wherein mapping comprises analyzing the light waves to determine the topography and proximity of the hard biological tissue and an environment around the hard biological tissue to the tool,
wherein identification comprises analyzing the correlation of reflected light waves to one or more biological tissue spectral signatures, and
on the basis of the processing, control the positioning means and the tool to work the hard biological tissue; and
wherein the system is adapted to be used to perform arthroplasty and revisions.
