Augmented reality system and method for spectroscopic analysis

A wearable spectroscopy system comprising:

• a head-mounted display removably mountable on a user's head;
• one or more light sources coupled to the head-mounted display system and configured to emit light in an irradiated field of view;
• one or more electromagnetic radiation detectors coupled to the head-mounted display system and configured to receive reflected light from a target object irradiated by the one or more light sources within the irradiated field of view;
• an anti-scatter grid disposed between the electromagnetic radiation detector and the target object, the anti-scatter grid configured to attenuate at least one of scattered light and ambient light incident thereon;
• one or more processors;
• and
• one or more computer storage media storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
• emitting, from the one or more light sources, light of a first wavelength in an irradiated field of view;
• detecting, at the one or more electromagnetic radiation detectors, light of the first wavelength reflected from a target object within the irradiated field of view;
• identifying, based on an absorption database of light absorption properties of at least one material, a material characteristic of the target object;
• and
• causing a graphics processor unit to display, to the user, an output associated with the material characteristic.

• identifying, based on an absorption database of light absorption properties of a plurality of materials, a material characteristic of the target object;
• and
• displaying, to the user, an output associated with the material characteristic.
