    Abstract: A microscopic Raman device includes: a sample set unit that has a cover which is openable and closable, and that stores a sample therein; a first laser light source that generates first laser light to be projected onto the sample; a shutter disposed on a first light path which is a light path of the first laser light from the first laser light source to the sample; a shutter drive unit that opens and closes the shutter; and a sensor. The shutter drive unit is configured to close the shutter when the sensor senses that the cover starts to be opened. The shutter blocks the first laser light when closed.

    Abstract: A device, for emitting and controlling infrared light, comprises a substrate extending between a bottom surface and a top surface. A cavity is provided in the substrate, the cavity opening onto the top surface. A light source extends over the cavity and is able to heat up when passed through by an electric current, so as to emit infrared light. A cover covers the substrate, the cover and the substrate forming a first component enclosing the light source. The light source delineates a first half space comprising the cover, and a second half space comprising the cavity and the bottom surface of the substrate.

    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 multiband IR adjunct (MIRA) sensor to spectroscopically determine the content and the concentration of chemical composition of a targeted object, includes a sensor housing, a first front optics in a first optical channel, a second front optics in the first optical channel, an acousto-optic tunable filter (AOTF), a photo detector (PD), a set of back optics in the first optical channel that focuses polarized narrow-band light beams received from the AOTF device onto the PD, the PD converting the polarized narrow-band light beams into an electrical signal, and a data acquisition unit signal-connected to the PD, the data acquisition unit collecting the electrical signals. Multiple optical channels can be provided within the housing to analyze UV/VIS/near infrared (NIR), short-wavelength infrared (SWIR), mid-wavelength infrared (MWIR), and LWIR wavelength ranges respectively.
