Embodiment Construction

[0050] The multi-angle multi-channel detection device of the present invention is a high-density multi-channel spectral imaging device, which also includes a light collector and a multi-channel kernel module that can collect light at different angles. The light collector is mainly composed of multi-core optical fiber bundles.

[0051] image 3A schematic structural diagram of the multi-angle multi-channel detection device of this embodiment is shown. In this embodiment, the multi-core optical fiber bundle 230 as a light collector may include a plurality of optical fiber probes 234-1, 234-2, ..., 234-7 and a plurality of optical fibers 232-1, 232-2, ..., 232-7 constituted. The multi-core fiber optic bundle 230 is then optically coupled to the multi-channel core module 214 . Here, for the sake of simplicity, seven channels are taken as an example, but the number of channels can be increased or decreased according to actual operation needs.

Abstract

The invention is used for detecting one or more samplers. It comprises a light collector and a multi-channel core module. The light collector has multi optical fiber probes each arranged in vertical direction or sloping direction with the sampler direction and used for collecting the light signals from the sampler. The multi-channel core module is connected to the light collector and used to makedetection for the sampler; the light collector is used to make beam incident into the multi-channel core module to be parallel with the optic axis of the multi-channel core module in order to get thespectral information about each channel.

Description

technical field [0001] The present invention relates to a sample detection device, and in particular to a multi-angle multi-channel detection device. Background technique [0002] LCD panel inspection technology includes the measurement of optical parameters such as chromaticity and luminance, which play an extremely important role in the quality control of LCD displays. Especially under the trend of larger panel area and faster manufacturing process in recent years, fast and accurate detection has become more and more important. At present, traditional panel testing devices can be divided into two types: single-point Fourier optical panel measuring devices and multi-point spectroscopic panel measuring devices. [0003] figure 1 Shown is the technique disclosed in US Patent No. 6,804,001. This device is based on the principle of Fourier optics combined with a spectroscopic image spectrum measurement structure. The light emitted by the object under test 2 passes through t...
