Abstract
A mannikin-based optical analyzer for analyzing an exposure of a subject to an environmental lighting condition. The analyzer has a mannikin with an outer surface replicating a facial profile of the subject, an interior inside the outer surface, and at least one pupil for admission of light into the interior of the mannikin. The analyzer has at least one optical detector configured to acquire and wavelength analyze light directed through the at least one pupil.
Claims23
A mannikin-based optical analyzer for analyzing an exposure of a subject of a population or a sub-population to an environmental lighting condition, comprising:
- a mannikin
- at least one pupil disposed in an eye socket of the mannikin for admission of light into the mannikin;
- the mannikin comprising a) an outer laterally-extending surface replicating a face and a facial profile of a surrogate head of the subject of the population or the sub-population being analyzed, and b) an interior inside the outer laterally-extending surface;
- and
- at least one optical detector configured to acquire and wavelength analyze light directed through the at least one pupil,
- wherein the at least one optical detector comprises
- a first optical detector configured to a) collect foveal light directed to a first position opposing the at least one pupil and b) wavelength analyze the foveal light into a foveal-light spectrum, and
- a second optical detector configured to a) collect retinal light angularly directed from the at least one pupil directly to a second position angularly offset from the first position and b) wavelength analyze the retinal light into a retinal-light spectrum.
An ambient light sensor, comprising:
- at least one pupil disposed in an eye socket of the mannikin for admission of light into the mannikin, the mannikin comprising a) an outer laterally-extending surface replicating a face and a facial profile of a surrogate head of a subject of a population or a sub-population being analyzed, and b) an interior inside the outer laterally-extending surface,
- an optical detector collecting ambient light and configured to wavelength analyze the ambient light into an ambient-light spectrum, the optical detector comprising a first optical detector configured to a) collect foveal light directed to a first position opposing the at least one pupil and b) wavelength analyze the foveal light into foveal-light spectra from a plurality of subjects, and a second optical detector configured to a) collect retinal light angularly directed from the at least one pupil directly to a second position angularly offset from the first position and b) wavelength analyze the retinal light into retinal-light spectra from the plurality of subjects;
- a processor storing the foveal-light spectra and the retinal-light spectra from the plurality of subjects under different environmental lighting conditions as pre-recorded foveal-light spectra and retinal-light spectra;
- and
- the processor programmed to select one of the pre-recorded foveal-light spectra and retinal-light spectra based on a) an identification of a specific lighting condition, b) a specific subject being exposed to the ambient light, and c) the ambient spectrum.
