Embodiment 1

[0057] In order to solve the existing technical problems, this embodiment proposes to use the screen of the mobile device to emit single-wavelength light as a light source for spectrum detection to illuminate the target, use the spectral imaging acquisition device to obtain the reflection spectrum information of the target, and use the spectral fitting algorithm to achieve Acquisition of target full spectrum band information.

[0058] The spectral fitting algorithm is a specific fitting algorithm, and its purpose is to convert the reflection spectrum information at a specific wavelength into the reflection information of the spectral response range. It is based on the fact that the ideal spectral response of each spectral segment is affected by the lighting condition, and the theoretical value response of each response spectral segment under the lighting condition is calculated, and the result is the fitting spectral camera response result under the specific lighting condition....

Abstract

The invention belongs to the technical field of spectrum detection, and particularly relates to a spectrum demodulation system and a spectrum demodulation method based on a screen light source of mobile equipment. The spectrum demodulation system utilizes a screen of the mobile equipment terminal as a light source for spectral imaging detection, emits light of different wavelengths by adjusting the screen, serves as a light source of a spectral imaging system, realizes illumination on a target, acquires a spectral image system by using spectral imaging equipment, and obtains spectral information of the target at different wavelengths by adopting a spectral fitting algorithm. Compared with the prior art, the common portable mobile equipment screen can serve as the light source, a complex light source environment composed of the conventional optical structure is replaced by means of fitting the portable mobile equipment screen and software, thereby providing portability, being small in size and light in weight, and being capable of being used in different scenarios.

Description

technical field [0001] The invention belongs to the technical field of spectrum detection, and in particular relates to a spectrum demodulation system and method based on a screen light source of a mobile device. Background technique [0002] With the rapid development of spectral technology, spectral technology has gradually entered people's daily life from the laboratory stage. Spectral imaging technology is a new method that organically combines traditional two-dimensional imaging technology and spectral analysis technology. According to The reaction of substances to electromagnetic waves of different wavelengths is used to identify and measure substances. The spectral imaging system can obtain a three-dimensional spectral image with the characteristics of "integration of graph and spectrum", which can not only observe the spatial information of two-dimensional distribution, but also observe the spectral information on each pixel point, [0003] Due to the limitations of...
