1. A method comprising:
causing one or more head-mounted light sources of a head-mounted display system to emit light in an irradiated field of view;
causing one or more electromagnetic radiation detectors, which are configured to receive reflected light from a target object irradiated by the one or more head-mounted light sources within the irradiated field of view, to detect light from the irradiated field of view including the target object;
determining an ambient light correction by detecting ambient light levels;
applying the ambient light correction to the detected light to determine levels of light absorption related to the emitted light and reflected light from the target object;
identifying, based on the levels of light absorption, a characteristic of the target object; and
displaying an output associated with the characteristic of the target object to a user on the head-mounted display system.
