The present invention relates to a pulse detector. The pulse detector comprises a light source, a light sensor and a sensing circuit. The light source is configured on a skin tissue of a living body, and generates at least a first light to irradiate on the skin tissue, and the first light will form a first light by reflection of the skin tissue the light sensor is configured on the skin tissue, and there is an interval between the light sensor and the light source, and the light sensor received the second light and, the sensing circuit is connected with the light sensor, and correspondingly generates a sensing signal according to the second light received by the light sensor, and the sensing signal is corresponded to a pulse variation of the living body in which, the interval is corresponded to a wavelength or brightness of the first light and the second light. Thus, the present invention may be used for realtime preliminary pulse determination, and the detector according to the present invention is simple and more convenient than the ordinary pulse detector.本發明係有關於一種脈搏感測裝置,該脈搏感測裝置包含一光源、一光感測器與一感測電路。該光源設置於一活體之一皮膚組織上,並產生至少一第一光線而照射至該皮膚組織,該第一光線經該皮膚組織反射而形成一第二光線;該光感測器設置於該皮膚組織上,該光感測器與該光源之間具有一間距,該光感測器接收該第二光線;以及該感測電路連接該光感測器,並依據該光感測器所接收之該第二光線而對應產生一感測訊號,該感測訊號對應於該活體之一脈搏變化;其中,該間距對應於該第一光線與該第二光線之波長或亮度。如此本發明可用於即時初步判斷脈搏,且本發明之檢測裝置相較於一般脈搏檢測裝置較為簡便。
