Abstract:
Methods, apparatuses, and systems for detecting and classifying individual airborne biological and non-biological particles, in real time, based on particle size and polarized elastic scatter. Auto-fluorescence content may also be used along with particle size and polarized elastic scatter for further orthogonal classification. With polarized elastic scattering, the degree of linear or circular depolarization produced from particle morphology, refractive index, internal asymmetric structures and molecular optical activity can be used for classifying individual airborne particles. Alternatively, circular intensity differential scattering (CIDS) or linear intensity differential scattering (LIDS) can be used to discriminate individual particles.

Claim (Index 27):
The method of  claim 26 , wherein:\n (a) if the first value is a depolarization value, determining the depolarization value by using at least one of the following equations:\n (i) \u03b4 N =[I V ]/[I H +I V ] where \u03b4 N  represents normalized depolarization, I H  represents the elastic scatter intensity for horizontally polarized light and is the same as the polarization state of the illumination beam and I V  represents the elastic scatter intensity for vertically polarized light; \n (ii) \u03b4=I HV /I HH  where \u03b4 represents depolarization, I HH  represents the elastic scatter intensity for horizontally polarized light and horizontally polarized incident beam, I HV  represents the elastic scatter intensity for horizontally polarized light and a vertically polarized incident beam; \n (iii) \u03b4 +C =[I \u22a5 ]/[I \u2225 +I \u22a5 ] where \u03b4 +C  represents circular depolarization when using right handed circularly polarized light as the illumination source, I \u22a5  represents the elastic scatter intensity for perpendicularly polarized light and I \u2225  represents the elastic scatter intensity for parallel polarized light; \n (iv) \u03b4 \u2212C =[I \u2225 ]/[I \u2225 +I \u22a5 ] where \u03b4 \u2212C  represents circular depolarization when using left handed circularly polarized light as the illumination source, I \u22a5  represents the elastic scatter intensity for perpendicularly polarized light and I \u2225  represents the elastic scatter intensity for parallel polarized light; and, \n (b) if the first value is an intensity differential elastic scattering value, determining the intensity differential elastic scattering value by using at least one of the following equations:\n (i) [I L (\u03b8)\u2212I R (\u03b8)]/[I L (\u03b8)+I R (\u03b8)] where I L (\u03b8) is the light scattered at angle \u03b8 when the incident beam is left circularly polarized and I R (\u03b8) is the light scattered at angle \u03b8 when the incident beam is right circularly polarized; and, \n (ii) [I H (\u03b8)\u2212I V (\u03b8)]/[I H (\u03b8)+I V (\u03b8)] where I H (\u03b8) is the light scattered at angle \u03b8 when the incident beam is horizontally polarized and I V (\u03b8) is the light scattered at angle \u03b8 when the incident beam is vertically polarized.
