An analysis and observation device includes: an electromagnetic wave emitter that emits a primary electromagnetic wave; a reflective object lens having a primary mirror provided with a primary reflection surface reflecting a secondary electromagnetic wave and a secondary mirror provided with a secondary reflection surface receiving and further reflecting the secondary electromagnetic wave; first and second detectors that receive the secondary electromagnetic wave and generate an intensity distribution spectrum; and a controller that performs component analysis of a sample based on the intensity distribution spectrum. A transmissive region through which the primary electromagnetic wave is transmitted is provided at a center of the secondary mirror. The transmissive region transmits the primary electromagnetic wave, which has been emitted from the electromagnetic wave emitter and passed through an opening of the primary mirror, thereby emitting the primary electromagnetic wave along an analysis optical axis of the reflective object lens.

A method and a device for detecting plastic foreign objects with low chromaticity difference in shredded tobacco through online pulse spectral imaging are provided. The method includes three steps: negative pressure thin-layer loading of shredded tobacco, pulse line-scanning identification of shredded tobacco, and positive pressure online elimination of foreign objects. Loose shredded tobacco is formed into a fixed and continuous thin layer on a surface of a conveying cylinder under the effect of a negative pressure adsorption force. The surface of the conveying cylinder is coded by areas. An LED linear array light source containing characteristic wavelengths of plastics with low chromaticity difference emits optical pulses, and a line-scanning camera is used to obtain characteristic signals of the plastic foreign objects with low chromaticity difference efficiently in real time.

Surface sensing methods for imaging a scanned surface of a sample via sum-frequency vibrational spectroscopy are disclosed herein. The methods include exposing a sampled location of the scanned surface to a visible light beam and exposing the sampled location to a tunable infrared beam such that the tunable infrared beam is at least partially coincident with the visible light beam. The methods also include varying a frequency of the tunable infrared beam an inducing optical resonance within an imaged structure that extends at least partially within the sampled location. The methods further include receiving at least a portion of an emitted light beam from the sampled location and scanning the visible light beam and the runnable infrared beam across the scanned portion of the scanned surface. The methods also include generating an image of the scanned portion of the scanned surface based upon the receiving and the scanning.
