Abstract: The invention provides a time-division multispectra detection device and method. The time-division multispectra detection device includes a plurality of light-emitting units of different wavelengths sequentially activatable by a control unit to emit one same wavelength of light onto an object at one same time. When one light-emitting unit is activated, the control unit synchronously activates the digital image sensing unit to obtain an image data of the object corresponding to one single wavelength of light from one respective light-emitting unit. After every spectrum image data is collected. A judgment of the human physiological characteristics of the object is performed, effectively reducing the overall costs.

Abstract: The present invention belongs to the field of laser plasma emission spectrometry, and in particular relates to a method for improving the detection sensitivity on a carbon element in laser-induced breakdown spectroscopy. The method specifically comprises the following steps: ablating the surface of a sample to be tested by using a laser beam emitted so as to rapidly heat the surface of the sample and the ambient air close to the surface of the sample into plasma, atomize carbon in the sample and nitrogen in the ambient gas, and combine carbon with the nitrogen into C—N radicals; tuning a wavelength-tunable laser to a wavelength needed by stimulated absorption transition of C—N radicals, and outputting a laser beam to radiate the plasma so that stimulated absorption transition of C—N radicals is carried out, then fluorescent signals are emitted with spontaneous radiative transition; collecting and recording an emission fluorescence spectrum of the C—N radicals; and qualitatively or quantitatively analyzing on carbon element. By adopting the method provided by the invention, in a case of hardly affecting the matrix spectrum, C—N radical signal can be enhanced in high selectivity, thereby avoiding the interference generated by the matrix, and spectrum signals of the carbon element in the plasma can be enhanced, thereby improving the detective sensitivity of LIBS on carbon element.

Abstract: A method of controlling a spectroscopic module that includes a measurement light source, a variable-wavelength optical filter, a photodiode, and a conversion circuit for converting a drive signal voltage into a gap displacement amount. The spectroscopic module has a reference light source for emitting a reference light beam of a known wavelength. The controlling method involves varying a gap for the incident reference light beam, extracting two maximum points among data output from the photodiode, and updating a first conversion formula provided in the conversion circuit through use of drive signal voltages and gap amounts corresponding to the two points.
