Abstract

The invention discloses a surface light scattering measuring device comprises a laser, a chopper, an attenuator, an integrating sphere, a phase locking amplifier, a receiver and a digital voltmeter, wherein the light emitted by the laser passes the chopper, then passes the attenuator, enters the integrating sphere and illuminates the surface of a sample; the light is reflected by the sample and received by the receiver; a detector and a pre-amplifier are arranged on the integrating sphere; the chopper is connected with the phase locking amplifier; the phase locking amplifier is connected with the detector and the pre-amplifier; the phase locking amplifier is further connected with the digital voltmeter. According to the surface light scattering measuring device, as the laser light source is adopted, the surface light scattering measuring device is especially useful and the procession is high; the laser light source is particularly suitable for providing high-quality monochromatic source, the surface light scattering can be measured quickly and effectively; surface light scattering measuring device has the advantages that the structure is simple, the measurement result is accurate, the operation is simple and the applicability is high.

Description

[0001] technical field [0002] The invention relates to a surface measurement device, in particular to a surface light scattering measurement device. Background technique [0003] The inhomogeneous clumps in the material make the light entering the material deviate from the incident direction and scatter in all directions. This phenomenon is called light scattering, and the light that disperses in all directions is called scattered light. Like the absorption of light, the scattering of light also reduces the intensity of the light passing through the material. Due to the existence of particles of other substances in the medium, or due to the inhomogeneity of the density of the medium itself (that is, density fluctuations), the phenomenon of light scattering is widely used in various scientific and technological departments. Through the measurement of scattered light, the concentration, size, shape and orientation of scattered particles can be known, and it has been applied...
