Towards a framework for light-dosimetry studies: Methodological considerations

Marilyne Andersen, Forrest Simon Webler, Steffen Lutz Hartmeyer

For field research of non-visual effects of light, accurate measurement of personal light exposure is required. A consensus framework for light-dosimetry could improve non-visual field research and ensure comparability between studies. Here, we present a r ...

Towards ‘Fourth Paradigm’ Spectral Sensing

Marilyne Andersen, Forrest Simon Webler, Manuel Spitschan

Reconstruction algorithms are at the forefront of accessible and compact data collection. In this paper, we present a novel reconstruction algorithm, SpecRA, that adapts based on the relative rarity of a signal compared to previous observations. We leverag ...

System and method for transcoding spectral data with task-based optimization via symmetric non-negative matrix factorization

Forrest Simon Webler

A computer-implemented method for reconstructing/recovering high-resolution visible light spectral data at a target resolution d, that comprises obtaining a configuration of a low- resolution multi-channel imaging sensor of resolution p, the configuration ...

Measurement in the Age of Information

Marilyne Andersen, Forrest Simon Webler

Information is the resolution of uncertainty and manifests itself as patterns. Although complex, most observable phenomena are not random and instead are associated with deterministic, chaotic systems. The underlying patterns and symmetries expressed from ...

Theory and application of a data-driven approach to compressive spectrometry in the assessment of neurophotic stimulation

Forrest Simon Webler

Recent advances in biology and neuroscience have elucidated pathways in which visible light initiates a signaling process, via the eye, responsible for activating direct and indirect biological responses. While the full impact of unnatural light patterns o ...

Spectral Measurement and Classification in the Era of Big Data

Marilyne Andersen, Forrest Simon Webler

The measurement and classification of light is essential across many scientific disciplines. Devices used to measure light range from the highly precise scanning spectroradiometers to the more practical compact multichannel filter-array type imaging sensor ...

Towards a wearable sensor for spectrally-resolved personal light monitoring

Marilyne Andersen, Giorgia Chinazzo, Forrest Simon Webler

Given the large impact that the spectrum and intensity of light can have on people's health and well-being, it is of fundamental importance to understand the properties of light received under normal living conditions. Historically, as research into the bi ...

What is the 'spectral diet' of humans?

Marilyne Andersen, Forrest Simon Webler, Manuel Spitschan

Our visual perception of the world - seeing form and colour or navigating the environment - depends on the interaction of light and matter in the environment. Light also has a more fundamental role in regulating rhythms in physiology and behaviour, as well ...

Audemars Piguet - Electrochromic Glazing Study

Marilyne Andersen, Victoria Eugenia Soto Magán, Forrest Simon Webler

The purpose of this report is to detail the findings of a long-term evaluation study on the impact of installing electrochromic glazing in two different buildings owned by Audemars Piguet. The two locations under investigation are the APRP ateliers in Le L ...

Perceived and yet not seen: non-visual effects in daylit spaces

Marilyne Andersen, Victoria Eugenia Soto Magán, Forrest Simon Webler

Findings from neuroscience are increasingly interwoven with architectural research (1,2). Understanding physiological responses to environmental stimuli in the built environment is critical when evaluating occupant health and wellbeing. Research in the fie ...

EPFL Smart Glass Field Study

Marilyne Andersen, Victoria Eugenia Soto Magán, Forrest Simon Webler

The objectives of this study are to evaluate (1) direct non-visual effects of red-impoverished daylight on circadian resetting and alertness and (2) the daily light-exposure pattern on indirect–circadian–effects. The novelty of this study is that it will b ...
