    摘要: A particle detecting method which is capable of detecting the number of low-speed particles accurately, and a storage medium storing a program for implementing the method. Intensity of scattered light generated when a light emitted into a gas stream is scattered by a particle is measured using a light receiving sensor at predetermined time intervals. A measuring time period for measuring the scattered light intensity is divided into measurement periods each defined as a predetermined time period, and a measured time point in each measurement period is selected at which a maximum value of the scattered light intensity measured is measured. The number of particles having passed by in front of the light receiving sensor is counted based on the measured time point selected in each measurement period.

    摘要: A light source section outputs optical flux having two types of wavelength, which are a short wavelength and a long wavelength, while the intensity is made variable. The output from the first light intensity detecting section in irradiating the optical flux having a short wavelength is compared with the output from the first light intensity detecting section in irradiating the optical flux having a long wavelength. A disappearance level near a point where the detected signal from the internal subject disappears is calculated. The first intensity of optical flux having a long wavelength is set to level higher than the disappearance level. Based on the output from the first light intensity detecting section obtained by the optical flux having a long wavelength of the first intensity, a subject inside the body to be detected is measured.

    摘要: A light source section outputs optical flux having two types of wavelength, which are a short wavelength and a long wavelength, while the intensity is made variable. The optical flux is made incident to a detected surface of a body to be detected at a predetermined incident angle simultaneously or alternatively. Based on a type of optical flux outputted from the light source section and an output from a first light intensity detecting section, at least the intensity of the optical flux having a long wavelength outputted from the light source section is adjusted. The output from the first light intensity detecting section in irradiating the optical flux having a short wavelength is compared with the output from the first light intensity detecting section in irradiating the optical flux having a long wavelength. A signal that appears only in the output from the first light intensity detecting section in irradiating the optical flux having a long wavelength is identified as a detected signal from an internal subject. The intensity of optical flux having a long wavelength is adjusted. A disappearance level near a point where the detected signal from the internal subject disappears is calculated. The first intensity of optical flux having a long wavelength is set to level higher than the disappearance level. Based on the output from the first light intensity detecting section obtained by the optical flux having a long wavelength of the first intensity, a subject inside the body to be detected is measured.
