    • PURPOSE: A pulse type optical fiber laser is provided to obtain a mode locked pulse or a Q switching pulse signal as oscillating a number of wavelengths at the same time. CONSTITUTION: An isolator(30) circulates an optical signal along one direction in an erbium-doped optical fiber(10) which is a gain medium optical fiber. A laser diode(20) pumps the optical signal to the erbium-doped optical fiber. An all optical fiber phase modulator(40) shifts a Doppler frequency in a laser optical signal by modulating the length of a resonator periodically. A Fabry-Perot periodic filter(50) filters a multi-wavelength pulse signal outputted from the all optical fiber phase modulator. A band pass filter(60) filters spectrum of the optical signal generated in the erbium-doped optical fiber.

    • An apparatus for generating a spatial-light-modulated laser signal is provided to accurately acquire position information, when an object moves at a constant speed, by periodically transmitting the spatial-light-modulated laser signal to the object. A spatial-light-modulated laser signal generator(110) periodically generates spatial-light-modulated laser signals in horizontal and vertical directions. A spatial-light-modulated laser signal transmitter(160) adjusts a focus of the spatial-light-modulated laser signal and outputs the result. The spatial-light-modulated laser signal generator includes a laser device(120), a first light speed increasing unit(130), a modulating plate(140), and a first prism(150). The modulating plate modulates the laser signal from the first light speed increasing unit in the vertical direction. The first prism changes a direction and a position of the spatial-light-modulated laser signal and reapplies the spatial-light-modulated laser signal into the modulating plate, such that the spatial-light-modulated laser signal is modulated in the horizontal direction by the modulating plate. The spatial-light-modulated laser signal transmitter includes a second prism(170), a second light speed increasing unit(180), and a zoom lens(190).
