摘要： PURPOSE: A portable sensor calling device using a rotation reflector filter is provided to achieve a light source part with a simple combination of individual optical devices and to achieve a signal processing part with an embedded system. CONSTITUTION: A portable sensor calling device using a rotation reflector filter comprises: a tunable laser(110) which filters the optical signal with the other wavelength according to the rotation angle while revolving at a specific speed and outputs the optical signal in which the wavelength is successively varied in the wavelength variable bandwidth; a first optical circulator(120) which induces the optical signal which is outputted from the tunable laser to an optical sensor; an optical detector(130) which converts the detected optics signal which is induced through the first optical circulator into the electric signal; and a call signal processor(140). The first optical circulator receives the detected optical signal which is reflected from the optical sensor and induces the optical signal to the optical detector. The physical quantity which is added to the optical sensor and the resonance wavelength of the optical sensor are produced by the comparison of the rotating angle of the rotation reflector filter and the intensity of the optical signal which is outputted from the optical detector.
