Biological aerosol particle detector |
| abstract |
A particle detector (10) includes a housing (12) defining a chamber (14), and an air flow ejector (16) that generates an air flow with entrained particles (20) in the chamber. The light source (22) generates a light beam (24) that intersects the air flow and is wider than the air flow. A light detection assembly (40) detects light generated by scattering of the light beam by particles in the air stream. A digitizer (38) generates a sequence of scattered digital values, each digital value representing light detected per a first unit duration. In addition, a summation component (39) generates a sequence of summed scatter digital values (41), each summed scatter digital value being equal to the sum of a sequential set of n digital values, and successive summed scatter digital values being offset by a first unit duration and overlapping the nearest neighbors by n-1 first unit durations. Finally, a detection component (42) processes the summed scattered digital values to detect particles. |
