Title: (DE) Reflektive Photodetektionsvorrichtung und Vorrichtung zur Messung biologischer Informationen
(EN) Reflection type photodetection apparatus, and biological information measuring apparatus
(FR) Appareil de photodétection de type à réflexion et appareil de mesure d'informations biologiques
Abstract: front page image
(EN) A biological information measuring apparatus (302) having a light emitting means (312) for emitting light to a wearer of the apparatus, and a photodetection means (33) for detecting light emitted by the light emitting means (312) into the body and generating a pulse wave signal according to the amount of detected light, said biological information measuring apparatus (302). The light emitting means (312) is arranged to emit light to the wrist or arm of the wearer of the apparatus; a filter (138) is arranged to filter light emitted by the light emitting means (312) and detected by the photodetection means (33), and is disposed between the light emitting means (312) and the wrist or arm and between the photodetection means (33) and the wrist or arm; and a transmission characteristic of the filter (138) is set so that the total wavelength range of light used for measurement by said biological information measuring apparatus (302) is within the range 500 nm to 600 nm.
