Problems solved by technology

Since the directionality of the scattered light is relatively discrete, and the scattering particles are easy to diffuse, and the size of the detector is generally fixed, it is always difficult to receive all the scattered light signals. Therefore, the intensity of the detection signal received by the detector Not strong enough, the detection accuracy is greatly limited

Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, the enhanced optical signal detection system of the present invention includes a light source 1 , a detection cavity 2 , a beam converging device 3 , a detector 4 and an optical trap 5 .

[0018] Wherein, the light source 1 is installed on the left side of the detection cavity 2 (for simplicity of description, the position and orientation are shown in the accompanying drawings), the light trap 5 is installed on the right side of the detection cavity 2, and the light source 1 and the light trap 5 are arranged on the on the same horizontal line. The detector 4 is installed inside the detection cavity 2 and its position is deviated from the light propagation path of the light source 1 . The beam converging device 3 is arranged around the inner wall of the detection cavity 2 and consists of two concave light-condensing spherical mirrors 31 and 32. The focal length is large, and the converging focal length of the concave concentrat...

Abstract

The invention discloses an enhanced light signal detection system. The enhanced light signal detection system consists of a detector, a detection cavity and a light source positioned on one side of the detection cavity, wherein two sides of the detection cavity, which are vertical to a light transmission direction of the light source, are respectively provided with a scattering particle inlet anda scattering particle outlet; one side of the detection cavity, which is opposite to the light source, is provided with a light trap; the detector is arranged in the detection cavity, and the position of the detector deviates from the light transmission path of the light source; and a beam converging device for converging scattering lights to the detector is also arranged in the detection cavity.The enhanced light signal detection system overcomes the defect that all scattering light signals are difficult to receive because the size of the detector is fixed, and has the advantages of sufficiently converging the scattering lights and improving the intensity of a detected signal received by the detector.

Description

technical field [0001] The invention belongs to the technical field of optical detection equipment, in particular to an enhanced optical signal detection system applied in a liquid phase detector. Background technique [0002] Light scattering occurs when a beam of light passes through a cavity filled with tiny particles. Since the directionality of the scattered light is relatively discrete, and the scattering particles are easy to diffuse, and the size of the detector is generally fixed, it is always difficult to receive all the scattered light signals. Therefore, the intensity of the detection signal received by the detector Not strong enough, the detection accuracy is greatly limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an enhanced optical signal detection system capable of fully converging scattered light and increasing the intensity of detection signals received by the detector, so as to overco...
