Abstract

The embodiment of the invention discloses an SPR (Surface Plasma Resonance) imaging detection device which comprises a base, an optical platform, an optical prism, a light source, an image receiving device, and a synchronous scanning device, wherein the synchronous scanning device comprises a motor, a sliding block guide rail, a sliding block, a connecting rod group, an incidence arm, and a reflection arm; the connecting rod group comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, and an circular arc guide rail; the first connecting rod and the second connecting rod are connected with the sliding block respectively; the first connecting rod and the second connecting rod form a reversed V-shaped rod; the third connecting rod is connected with the other end of the first connecting rod, and the first connecting rod and the third connecting rod form a V-shaped rod; the fourth connecting rod is connected with the other end of the second connecting rod, and the second connecting rod and the fourth connecting rod form a V-shaped rod; the circular arc guide rail is in sliding connection with the joint of the first connecting rod and the third connecting rod and the joint of the second connecting rod and the fourth connecting rod; the joint of the first connecting rod and the third connecting rod and the joint of the second connecting rod and the fourth connecting rod are kept sliding symmetrically along the circular arc guide rail. Therefore, the detecting precision of the SPR imaging detection device is improved.

Description

technical field [0001] The invention relates to the technical field of imaging detection, in particular to a surface plasmon resonance imaging detection device. Background technique [0002] The Surface Plasmon Resonance (SPR) sensor is a sensor that can detect subtle changes in the optical properties of the medium to be measured (such as medium thickness, refractive index, etc.), and its core component is a metal functional layer. When the incident light with a certain incident angle, wavelength and transverse magnetic (TM) polarization direction passes through a coupler such as a prism, it will excite a surface plasmon wave (Surface Plasmon Wave, referred to as for SPW). When the excitation efficiency of the surface plasmon wave is the highest, the SPR phenomenon will occur, that is, the intensity of the reflected light at the interface will be sharply attenuated or the polarization direction will change. change, to realize the detection of the optical properties of the ...
