Patent number: 10365221Abstract: Aspects of Raman spectrum plane imaging device(s), belonging to the technical field of Raman spectra, are disclosed. In one example, a Raman spectrum plane imaging device may comprise a laser generation apparatus capable of adjusting an output wavelength, a light filtering apparatus, and a planar array detector. Laser light beams emitted by such laser generation apparatus may irradiate on a surface of a sample in a planar illuminating manner. According to systems herein, Raman scattered light generated by the sample under the excitation of the laser light beams is incident on the light filtering apparatus and is imaged on the planar array detector after selectively passing through the light filtering apparatus, to be received by the planar array detector. In some implementations, the light filtering apparatus may comprise an F-P interference device and a band-pass light filter.Type: GrantFiled: March 19, 2018Date of Patent: July 30, 2019Assignee: Institute of Materials, China Academy of Engineering PhysicsInventors: Haibo Li, Wenhua Luo, Gan Li, Yuejiao Gu, Guangfeng Zhang, Pengfei Yang
