Abstract
A method for determining a distribution of events, a method for determining a distribution of particle sizes in a sample of air, and an apparatus for performing the same are provided. The method includes obtaining a measured ensemble property distribution function for one or more events, generating one or more theoretical ensemble property distribution functions based on Poisson statistics using one or more model parameters, and determining an event parameter property distribution function by fitting one or more of the theoretical ensemble property distribution functions to the measured ensemble property distribution function using a forward inversion algorithm.
Claims9
An apparatus comprising:
- a property distribution function (PDF) generating system comprising electronics;
- and
- an extinction probe including a housing, one or more mirrors, a light source and a detector, the detector configured to receive light that passes from the light source through an air sample;
- wherein the electronics are configured to determine a measured particle property distribution function (PDF) for one or more events using the extinction probe, generate one or more theoretical ensemble property distribution functions (PDF) based on Poisson statistics using one or more model parameters using the PDF generating system, and determine an event parameter property distribution function (PDF) by data fitting one or more of the theoretical ensemble PDFs to the measured particle PDF, wherein the one or more theoretical ensemble PDFs include at least one or more random distributions;
- wherein the detector and the light source are within the hosing and a path of the light is manipulated by the mirrors.
