Abstract

The invention relates to a gold spot quantitative determination optical device, which comprises an image acquisition sensor, a light source and a dark box; the image acquisition sensor and the light source are fixed on the inner surface of the dark box top; the image acquisition sensor is connected with the control rod; the top of the control rod passes through the dark box top and is connected with the data signal processor; the output terminal of the data signal processor is connected to the light source; a drawer is disposed on the bottom of the dark box with center opposite the image acquisition sensor; The data signal processor is utilized to control the light source intensity based on the pulse width modulation principle, provides a stable, clear, weak reflection and weak shadow environment, thereby improves image quality.

Description

technical field [0001] The invention relates to a device in the technical field of quantitative detection, in particular to an optical device for quantitative detection of gold-labeled spots. Background technique [0002] As we all know, test paper detection is a fast, portable, simple and easy detection method, and it has been widely used in the fields of biology, chemistry and medicine. Based on different color reaction principles, there is a monotonous but non-linear relationship between the color depth displayed after the test paper reacts with the test agent and the concentration of the test agent. Therefore, the test results cannot be judged solely by the experience of the observer, but must be measured with professional quantitative testing instruments to obtain true and credible calculation results. In the prior art, a gold-labeled spot quantitative detector based on colloidal gold technology provides a complete and reliable detection solution for human chorionic go...
