PURPOSE: A surface plasmon resonance sensor system is provided to attach a sample feeding part to a sensor chip because a control part for controlling distance is installed in the sample feeding part. CONSTITUTION: A surface plasmon resonance sensor system comprises a light source(100), a polarizing part(110), a rotary mirror(200), a shielding layer(300), a cylinder lens(400), a sensor chip(500), and a light receiving part(600). The light source generates a first light(120). The polarizing part polarizes the first light. The rotary mirror comprises a substrate and metal layers deposited on at least one surface. The shielding layer is arranged adjacently to the rotary mirror and a part of a second light(240) passes through the shielding layer. The cylinder lens collects the part of the second light passing through the shielding layer. The sensor chip a prism(510) and a metallic thin film(530) forming in one side of the prism. The light receiving part detects a third light(610).
