| titleOfInvention | Spectrum measurement device based on electro-optical effect and spectrum measurement method thereof |
| abstract | The invention discloses a spectrum measurement device based on the electro-optical effect. The spectrum measurement device based on the electro-optical effect comprises a first polarizing film, an electro-optical effect crystal, a second polarizing film and an optical detector all of which are sequentially arranged in the direction of incident light, wherein the polarizing direction of the first polarizing film is not parallel with the induction spindle direction of the electro-optical effect crystal under an external electric field. The invention further discloses a spectrum measurement method using the spectrum measurement device based on the electro-optical effect. The method comprises the steps that firstly, luminous power detected by the optical detector when different external impressed voltages are applied on the electro-optical effect crystal is measured, the obtained data of the luminous power serve as an augmented matrix, the augmented matrix is combined with a coefficient matrix formed by detectivity of the incident light of different frequencies from the spectrum measurement device under the different external impressed voltages, and then a linear system of equations is built; the linear system of equations is solved, the luminous power of each frequency component in the incident light to be detected is obtained, linear fitting and radiometric calibration are carried out on the luminous power, and the spectrum of the incident light to be detected is obtained. The spectrum measurement device based on the electro-optical effect and the spectrum measurement method have the advantages of being high in vibration resistance, high in resolution ratio, wide in spectrum measurement range and the like. |
