preparation example Construction

[0062] First carry out the preparation of silver colloid: the volume is 50m1 and the concentration is 1.0×10 -2 mol L -1 AgNO 3 Inject in the flask that 450ml water is housed, stir and be heated to boiling, inject 10ml percentage concentration then and be 1% sodium citrate solution, keep stirring and heat boiling 40 minutes, final colloid is yellow-green. Since the prepared silver colloid is negatively charged, it can be assembled by utilizing the electrostatic interaction between the positively charged electrolyte PDDA and the negatively charged silver particles.

[0063] The specific steps are as follows: first clean the glass substrate, ultrasonically clean the glass substrate in ethanol-acetone solution with a volume ratio of 1:1, ethanol and water for 20 minutes, then soak it in boiling Piranha solution for 30 minutes, take it out for use Rinse 3 times with deionized water, dry with argon, and the Piranha solution is made of 98% H 2 SO 4 with 30%H 2 o 2 Prepared at ...

Abstract

The invention discloses an imaging spectrometer based on scattering effects and a high spatial resolution spectral imaging method; the imaging spectrometer includes a front device, a scattering device, a collimation device, an array detection chip, a control device, and a data calculation and analysis system; The imaging spectrometer disclosed in the invention controls the scattering device through the control device. The light intensity detected by the same pixel element under different control conditions is different from each other. Substituting it into the matrix equation to calculate the spectrum can output more control parameters through the control device to realize Higher spectral resolution; due to the large number of pixels on the array detection chip, each pixel can be used as a separate detector for different subunit areas of the imaging area to be measured by dividing the target area Spectral measurements are performed, so the spatial resolution of spectral imaging is high. Compared with the traditional imaging spectrometer, the imaging spectrometer disclosed in the present invention has smaller volume, lower cost and higher performance.

Description

technical field [0001] The invention relates to an imaging spectrometer and a spectral imaging method for obtaining rich information of spatial dimension and spectral dimension, which can be used in the technical field of remote sensing and imaging with high spatial resolution and high spectral resolution. Background technique [0002] In modern optical testing and analysis methods, imaging and spectroscopy technologies play an important role, and imaging spectrometers can realize target object image and spectral distribution detection at the same time, expanding imaging and spectral analysis to new application fields. The imaging spectrometer can collect different numbers of grayscale images at the same time according to the different collection wavelength intervals, and the grayscale images of each spectral channel contain the spectral information of the target object in this band. Therefore, the image information and spectral information of the whole detection band can be...
