Problems solved by technology

Although the dispersion properties of the glass refractive index have been discussed, the dispersion effect of the glass is only considered as a source of error; the current refractive index matching method only measures the glass refractive index at a specific wavelength

Abstract

The invention discloses a detection system for refractive index refractive dispersion properties and a detection method thereof. The detection system for the refractive index dispersion properties comprises a transparent carrier (100) used for holding an object to be detected (110) and matching fluid (120), a temperature adjusting device (190) used for changing and acquiring the temperature of the transparent carrier (100), a broadband light source (200) used for emitting broadband light to the transparent carrier (100), an imaging device (300) used for forming a wavelength matching image of the transparent carrier (100) which at least contains two-dimensional information by the broadband light, and a computation processing device (400) used for converting the wavelength matching image of the transparent carrier (100) at least containing the two-dimensional information into a corresponding electric signal, and analyzing the electric signal by combining the temperature acquired by the temperature adjusting device (190) to obtain the refractive index refractive dispersion properties of the object to be detected (110).

Description

technical field [0001] The invention relates to a detection system and a detection method for the dispersion characteristic of the refractive index. Background technique [0002] Dispersion properties are an important indicator of transparent materials, such as glass, and are related to the composition of the glass and its manufacture. Therefore, glasses from different manufacturers, formulations, raw materials and production batches can be identified by their dispersion characteristics. In addition, the measurement of the dispersion characteristic of the refractive index of glass has important application value in the fields of industrial material detection, forensic evidence identification and so on. [0003] The traditional measurement method of glass refractive index dispersion characteristics is based on the measurement method of glass refractive index, respectively illuminating the sample with monochromatic light of different wavelength bands, obtaining the refractive...
