Abstract: |
Its method includes the following steps: changing the beam emitted by broadband light source into a hairline beam; making said hairline beam be irradiated on SPR generation device; after the beam outcome from said device is dispersed, utilizing two-dimensional photoelectric detection device to make detection and obtain SPR spectrum information in a lighted line-type region of tested plane; translating said device and using said hairline beam to scan the whole tested plane to obtain SPR spectrum information of all the columns of whole tested plane; utilizing computer to make operation and processing to obtain refractive index information of whole tested plane in said device so as to form a two-dimensional image. Said method can be used for detecting various biological chips. |
