摘要： PROBLEM TO BE SOLVED: To achieve a terahertz wave-generating device which can easily constitute a spectroscopic device.
SOLUTION: Signal light from a signal light source 10 and pump light from a pump light source 11 are multiplexed by a nonpolarization beam splitter 12 to generate multiplexed light, and the multiplexed light is amplified by a fiber amplifier. Then, the multiplexed light is divided into multiplexed light (A) and multiplexed light (B) by a polarization beam splitter 15, and the multiplexed light (A) and the multiplexed light (B) are mixed by a polarization beam splitter 16 so that they may overlap in a GaP crystal 17 with a phase matching angle which they form. By this, the terahertz wave by the difference frequency mixing of the pump light in the multiplexed light (B) with the signal light in the multiplexed light (A) and the terahertz wave by the difference frequency mixing of the pump light in the multiplexed light (A) with the signal light in the multiplexed light (B) are radiated in two directions. One of the terahertz waves radiated in the two directions can be the reference light, and accordingly a spectroscopic device can easily be constituted.

摘要： PROBLEM TO BE SOLVED: To provide a radar apparatus capable of measuring an orientation of an object in a short time and with high accuracy.SOLUTION: A radar apparatus comprises: signal generating means 10; a phase shifter 20; transmission antennae 40-1-40-4; a receiving antenna 50; and signal processing means 70. Three signals whose frequencies are orthogonal to one another are generated and output. The three signals are divided into four parts, and are output to the transmission antennae 40-1-40-4 when phase differences are respectively controlled and then combined. The transmission antennae 40-1-40-4 simultaneously emit beams toward three directions different for respective frequencies of the three signals. The signal processing means 70 performs a frequency analysis of a received signal, and measures an orientation of an object from signal strengths in frequencies of the three signals. By frequency orthogonality, beams can be simultaneously emitted to a plurality of directions without each of the beams being made to intervene. Further, a frequency band can be efficiently and effectively used as a narrow band.
