Abstract: The present invention provides a wide-filed spectral imaging system including a laser generator, a wavelength adjustment module, an objective lens, and a single-pixel imaging and a spectral separating module. The laser generator is configured to generate a laser excitation beam. The wavelength adjustment module is configured to disperse the laser excitation beam into a plurality of beams of different wavelengths. The objective lens is configured to focus the plurality of beams of different wavelengths on a sample to excite molecules under test in the sample and generate an emission light. The single-pixel imaging and spectral separating module is configured to generate a series of patterns and modulate the emission light with the series of patterns to generate a diffracted beam. The single-pixel imaging and spectral separating module further disperses the wavelength of the diffracted beam, collects light signals of the expanded diffracted beam, and performs a spectral image reconstruction.

Abstract: A sensing substrate including a substrate, a quantum well structure, a sensing surface and metal nanoparticles is provided. The quantum well structure is disposed on the substrate, and the quantum well structure includes at least one first metal nitride layer and second metal nitride layers. The first metal nitride layers and the second metal nitride layers are stacked on the substrate in alternation manner. The quantum well structure is located between the sensing surface and the substrate. The metal nanoparticles are disposed on the sensing surface, and the sensing surface is a rough surface. A manufacturing method of the sensing substrate and a sensor are also provided.
