摘要： A method and apparatus for surface plasmon resonance imaging are provided for imaging the surface plasmon resonance signals caused by the interaction of biomolecules. In particular, the method and apparatus can image the slightly spectral change in a surface plasmon resonance mode by comparing the light intensities of two bands in the frequency domain of the surface plasmon.

摘要： A curved diffraction grating includes a substrate and a metal layer. The substrate is a two-dimensional curved plate structure and has a first surface, a second surface and a plurality of microstructures. The first surface is disposed opposite to the second surface, and the microstructures are disposed on the second surface. Each of the microstructures is a saw-tooth structure and has a clear blazed angle. The metal layer is disposed on the microstructures and has a plurality of diffraction structures corresponding to the microstructures. A spectrometer containing the curved diffraction grating and a manufacturing method of the curved diffraction grating are also disclosed.
