    • A particulate determination method determines by onetime scanning, the size of a particulate included in a plurality of particulates of various sizes which are arranged on a disc. False recognition of the number of particulates is avoided even when a plurality of particulates are adjacent to each other. A photodector detection signal is judged using plural threshold values according to the sizes of particulates to be detected. Results of determinations corresponding to the respective threshold values are stored on mutually independent memory maps. When counting particulates, a particulate size and a particulate count value are determined from a combination of stored data appearing in a scanning window at the same position on the respective memory maps.
    • 微粒确定方法通过一次扫描来确定包括在布置在盘上的各种尺寸的多个微粒中的颗粒的尺寸。 即使当多个颗粒彼此相邻时,也避免了微粒数量的错误识别。 根据要检测的微粒的尺寸,使用多个阈值来判断光电检测器检测信号。 对应于各个阈值的确定结果存储在相互独立的存储器映射上。 当计算微粒时,从出现在各个存储器映射上相同位置的扫描窗口中的存储数据的组合确定颗粒尺寸和颗粒计数值。
