Method and system for advanced autofocusing spectroscopy

A spectroscopic autofocusing method comprising:

• applying a plurality of electrical signals to a shape changing lens of a spectroscopy system;
• determining, by a detector, one or more power measurements of one or more returned optical signals;
• and
• determining an optimized electrical signal corresponding to a maximum power measurement, wherein each power measurement of the one or more power measurements corresponds to a respective electrical signal of the plurality of electrical signals applied to the shape changing lens.

A spectroscopy system comprising:

• a shape changing lens coupled to a controller, wherein the shape changing lens is configured to optically couple to an optical source and a target;
• and
• a detector coupled to the controller, wherein the detector is configured to determine one or more power measurements of one or more returned optical signals returned by the target,
• wherein the controller is configured to:
• apply a plurality of electrical signals to the shape changing lens, and
• determine an optimized electrical signal corresponding to a maximum power measurement, wherein each power measurement of the one or more power measurements corresponds to a respective electrical signal of the plurality of electrical signals applied to the shape changing lens.
