Abstract
A system and method of detecting spores includes a light source configured to emit a light pulse within a first wavelength range, and a light sensor configured to detect a resulting phosphorescence emitted from one or more desiccated spores phosphorescing within a second wavelength range in a vicinity of the light pulse. The spore detector also includes circuitry configured to trigger emission of the light pulse and record the emitted phosphorescence at a pre-determined time after the light pulse.
Claims22
A spore detector, comprising:
- a light source configured to emit a light pulse within a first wavelength range;
- a light sensor configured to detect and record a resulting phosphorescence emitted from one or more desiccated spores phosphorescing within a second wavelength range in a vicinity of the light pulse;
- and
- circuitry configured to trigger emission of the light pulse and record the emitted phosphorescence at a pre-determined time after the light pulse.
1 more element
A method of detecting spores, the method comprising:
- flashing via a light source, a light within a first wavelength range;
- initiating via circuitry, a light sensor, wherein the light sensor is gated for a pre-determined time from the flashing light and is filtered to record emitted phosphorescence within a second wavelength range;
- and
- detecting via the light sensor, the emitted phosphorescence from desiccated spores within a vicinity of the flashing light at the pre-determined time.
1 more element
A spore detector system, comprising:
- one or more spore detectors configured to detect a presence of desiccated spores within a defined vicinity, wherein each spore detector includes
- a light source configured to emit a light pulse within a first wavelength range;
- a light sensor configured to detect a resulting phosphorescence emitted from the desiccated spores phosphorescing within a second wavelength range in a vicinity of the light pulse;
- and
- circuitry configured to trigger emission of the light pulse and record the emitted phosphorescence at a pre-determined time after the light pulse.
