ABSTRACT:
A
photoacoustic (PA) imaging that utilizes acoustic detection of sound generated
by a specimen due to the absorption of modulated light was applied to measure
the amount of the pollen of the Cryptomeria
japonica, Asian allergic plant.
High-sensitivity PA imaging can measure pollen particles with a large dynamic
range from single particle to several hundred micrograms. The PA signal
dependence on the amount of the pollen showed good correlation with the amount
of pollen.
