Problems solved by technology

[0008] Equally, this optical detection device 2 does not provide the moiré pattern because the penetrating pattern testing board 21, so if the data such as the degree of distortion and chromaticity of this optical lens module 22 are to be detected, the penetrating pattern must be replaced. Pattern test board 21, or reset the test environment
resulting in slower tests

Abstract

The invention relates to an optical detection device and a detection method for an optical lens module. The optical detection device includes a flat-panel display, an image sensor and a computer system that controls the flat-panel display to display different test patterns, the computer system is connected to the image sensor, and the optical lens module to be tested is located between the flat-panel display and the image sensor. Meanwhile, the test pattern displayed on the flat-panel display is imaged on the image sensor via the optical lens module to obtain image data corresponding to the different test patterns, and the image data is input into the computer system. The optical detection device and detection method of the present invention use a computer system to control a flat display to display different test patterns, which can make the detection process faster.

Description

technical field [0001] The invention relates to an optical detection device and a detection method, in particular to an optical detection device and a detection method for detecting an optical lens. Background technique [0002] In digital imaging products, the optical module is usually an indispensable component, and the quality of the optical lens in the optical module directly affects the display quality of the optical module and even the digital imaging product. [0003] A kind of optical detection device of prior art optical lens resolution (Resolution) such as figure 1 shown. The optical detection device 1 mainly includes a parallel light source 10 , a penetrating pattern test plate 11 and a linear charge coupled device (Charge Coupled Device, CCD) 13 . [0004] During detection, the optical lens module 12 is arranged between the penetrating pattern test plate 11 and the linear CCD 13, and the parallel light beam emitted by the parallel light source 10 passes through...
