ABSTRACT:
Disclosed herein is an optical detection method and optical detection apparatus, the apparatus including: a light irradiation section configured to irradiate a laser beam upon one of fine particles which are successively fed in a flow path; and a light detection section configured to detect fluorescent light and/or scattered light generated from any of the fine particles upon which the laser beam is irradiated; the method including the steps of: irradiating a laser beam upon one of fine particles which are successively fed in a flow path; and detecting fluorescent light and/or scattered light generated from the fine particle; wherein the laser beam being formed as a pulse laser beam whose pulse intensity is modulated such that one laser beam or two or more laser beams having different wavelengths are irradiated by a plural number of times upon one fine particle with the intensity varied.
