Abstract:
A particle detector that includes a housing defining a chamber, and an air stream injector, producing an airstream with entrained particles, in the chamber. A light source produces a light beam that intersects with and is wider than the air stream. A light detection assembly detects light generated by scattering of the light beam, by particles in the air stream. A digitizer produces a sequence of scattering digital values, each representing light detected per a first unit of time duration. Additionally, a summing assembly produces a sequence of summed scattering digital values, each equaling a sum of a sequential set of n of the digital values, and wherein successive summed digital values are offset by a the first unit of time duration and overlap by n−1 of the first units of time duration with a nearest neighbor. Finally, a detection assembly processes the summed scattering digital values to detect particles.

Claim (Index 1):
A bioaerosol detector, comprising:\n a. a housing, defining a chamber; b. an air stream injection assembly, that injects an air stream from outside said housing, into said chamber; c. an ultraviolet light source, producing a light beam that intersects said air stream; d. a first optical train, having:\n i. a first collimating lens, placed at an angle to the light beam; \n ii. a first wavelength-range pass filter, placed in line to said first collimating lens; \n iii. a first focusing lens, coaxial with the first collimating lens and focusing light transmitted by said long wave pass filter; and \n iv. a first light detector positioned to receive and detect light from said first focusing lens; \n e. a second optical train, having\n i. a second collimating lens, coaxial with said first collimating lens, on opposed side of said light beam; \n ii. a second wavelength-range pass filter, placed in line to said first collimating lens, and serving as a mirror to reflect first wavelength-range light and as a wavelength-sensitive window to only pass second wavelength-range light; \n iii. a second focusing lens, placed coaxial with second collimating lens and focusing light transmitted by said second wavelength-range pass filter; and \n iv. a second light detector positioned to receive and detect light from said second focusing lens; and \n f. wherein light reflected from said second wavelength-range pass filter is focused by said second collimating lens, and accepted by said first collimating lens, thereby increasing first wavelength-range light received by said first light detector.
