Title: Wavelength dispersion compensation for optical fiber transmission system and compensating fiber
Inventor: SILLARD PIERRE
IPC: H04B10/2525
Filed: 2001-10-15
Abstract: PROBLEM TO BE SOLVED: To propose the use of a dispersion compensating fiber for compensating a wavelength dispersion and a wavelength dispersion gradient in a line fiber in an optical fiber transmission system. SOLUTION: The dispersion compensating fiber satisfies equation (1): C2/C '2×1/1+Ccum/(Lg.C'gΔλ)<=C/C'<=Cg/C'g×1/1--Ccum/(Lg.C'g.Δλ) and equation (2): |C'/C"|>=Max(Δλ/2×(C.C'g/C',Cg×±Ccum/Lg.C'g/>=λ)--1)-1). These conditions assure compensations for the wavelength dispersion and the wavelength dispersion gradient in a broad band transmission system (e.g. C and L band transmission systems) with the wavelengths of 1,530 to 1,620 nm.

Inventor: UEHARA NAOHISA
IPC: G01S13/93
Filed: 2001-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain an on-vehicle radar device capable of suppressing the creeping effect of a transmission electromagnetic wave on a receiving means. SOLUTION: The electromagnetic waves generated by an oscillator 1 are subjected to PSK modulation by a modulator 2 to be emitted to space by a transmission antenna 4 and reflected by target matter 6 or other matter to be received by a receiving antenna 7. The received electromagnetic waves are subjected to IQ detection by an IQ detecting mixer 8. Both beat signals outputted from an I channel and a Q channel are multiplied by a multiplier 9 to output the voltage value corresponding to the phase difference between transmitting and receiving waves. An LO oscillator 10 outputs electromagnetic waves for LO to the mixer 8 while changes the frequency of electromagnetic waves corresponding to the voltage value to cancel the beat signal from matter other than the target matter 6.  By this constitution, a signal processor 14 calculates the distance and relative speed of the target matter 6 on the basis of the beat signal outputted from the Q channel of the mixer 8.
