PROBLEM TO BE SOLVED: To obtain a highly sensitive optical remote antenna capable of effectively receiving weak wave. SOLUTION: The optical remote sensor is constituted of a reflector antenna 11 concentrating wave transmitted in space in a specific location and raising energy density of the wave there, a light modulator placed in the specific location, a light source, a photodetector, an optical fiber 13a guiding the light from the light source to a modulator and an optical fiber 13b guiding the output light from the light modulator 12 to the photodetector 13b.
