Abstract: Arbitrarily-cut lace fabric of non-hot-melt material includes a fabric body knitted on a lace machine. The fabric body has a main body knitted by using two filament bars and two spandex bars. A pattern layer, formed by knitting an elastic yarn or filament following a weft insertion structure or a looping structure using a pattern bar, is provided on the main body, and an elastic weft opening layer, a warp opening layer and a tight resistance layer are further provided inside the main body. The present invention has the advantages of good tensile properties in the warp and weft directions, which can be stretched freely in all directions and is not prone to falling apart after being cut, and can be widely used in underwear, corsets. sports, and leisure clothing.

Abstract: 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.
