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.

Abstract: An optical system for particle detection. The system includes a sample inlet housing; a sample outlet housing; a detection cavity having an axially surrounding wall and disposed between the sample inlet housing and the sample outlet housing; a light source configured to irradiate light through the detection cavity to particles of a sample fluid flowing inside the wall of the detection cavity; a light detector for detecting the light that is scattered by particles of the sample fluid in the detection cavity; an alignment rail having a base and sidewalls which a) extend from the sample inlet housing to the sample outlet housing and b) connect the sample inlet housing to the sample outlet housing; and the alignment rail comprising a channel formed by the base and the sidewalls, the channel having a channel lateral width fitting to a housing width of at least one of the sample inlet housing and the sample outlet housing, whereby the sample inlet housing, the housing, and the sample outlet housing are held in alignment together.

Abstract: Sample monitoring and flow control systems and methods are disclosed for monitoring of airborne particulates. A system may include a particle collection filter. The system also includes a fluid moving device for moving a sample through the particle collection filter. Further, the system includes a light source configured to direct irradiating light towards the particle collection filter. The system also includes a light detector positioned to receive the irradiating light passing through the particle collection filter and configured to generate a signal representative of an amount of the received light. Further, the system includes a controller configured to receive the signal and to control the fluid moving device based on the amount of the received light.

Abstract: A particle detector includes a housing, a light source, and a photo-responsive material. The housing includes a sample inlet and a sample outlet, and encloses a detection cavity. The light source directs irradiating light along a longitudinal axis to particles of a sample fluid flowing in the detection cavity. The photo-responsive material surrounds at least a portion of the detection cavity, and receives measurement light propagating from the particles in a plurality of measurement light paths angled relative to the longitudinal axis. The particle detector may be utilized to measure scattered light and/or light emitted due to autofluorescence. Fluids sampled may include aerosols, bio-aerosols, and liquids.

Abstract: A particle detector includes a housing, a light source, and a photo-responsive material. The housing includes a sample inlet and a sample outlet, and encloses a detection cavity. The light source directs irradiating light to particles of a sample fluid flowing in the detection cavity. The photo-responsive material faces the detection cavity, and receives measurement light propagating from the particles in a plurality of measurement light paths angled relative to a longitudinal axis. The particle detector may be utilized to measure scattered light and/or light emitted due to autofluorescence. Fluids sampled may include aerosols, bio-aerosols, and liquids.
