1. A spectroscopy method comprising, under control of one or more processors of a wearable spectroscopy system:
causing one or more light sources of the wearable spectroscopy system to emit pulses of light with at least two different wavelengths to irradiate a target object;
receiving, from at least one electromagnetic radiation detector of the wearable spectroscopy system, one or more signals indicating detected levels of light absorption related to the emitted pulses of light and reflected light from the target object irradiated by the emitted pulses of light;
determining the output based on comparing the detected levels of light absorption with stored absorption data comprising light absorption properties of a plurality of materials and matching the detected levels of light absorption to one or more of the plurality of materials of the stored absorption data; and
causing the wearable spectroscopy system to display, to a user wearing the wearable spectroscopy system via a head-mountable display of the wearable spectroscopy system, an output based on the detected levels of light absorption.
