Abstract: Disclosed are a pulse laser generator and an optical fiber sensor system using the same. The optical fiber sensor system includes a main optical coupler that receives pulse laser light generated from a pulse laser generator from a first input terminal, branches the light to first and second output terminals to output, and outputs, through a third output terminal, light input reversely from the first and second output terminals, a reference optical fiber that is connected to the first output terminal, a multi-point sensing optical fiber unit that is connected to the second output terminal, and in which optical fibers are connected in series or in parallel corresponding to a plurality of sensing points, an optical detection unit that is connected to the third output terminal, and a diagnosis processing unit that detects a change of the physical quantity for the sensing points from signals from the optical detection unit.

Abstract: A multi-function spectroscopic device includes a first lens installed in an emission direction of parallel light and focusing the light in a center portion thereof, a second lens disposed to face the first lens and, a reference mirror installed to face the second lens, a beam splitter installed between the first lens and the second lens, a third lens focusing light which moves through the beam splitter onto a measurement object, a fourth lens focusing light which is reflected by the measurement object and reversely moves through the third lens and the beam splitter, a fifth lens converting light which is diffused through a second focus of the fourth lens into parallel light, and a diffraction grating obliquely disposed with respect to a light axis of the fifth lens and diffracting parallel light which moves through the fifth lens and split the parallel light.
