The invention discloses a ground stress test method for aperture distortion optical microscopy measurement. On the basis of ground stress tests of aperture distortion, a design scheme of a multi-contact-probe aperture distortion sensing structure is provided, so that aperture distortion is visual and digital. On the basis of an optical microscopy imaging technology, the technical purposes that micro aperture distortion is visually observed and digitally measured are achieved, and optical microscopy measurement of aperture distortion is achieved. On the basis of theoretical analysis on an aperture distortion principle, a ground stress calculation formula based on aperture distortion optical microscopy measurement is deduced, optimization analysis is carried out on the parameters and the layout of related technologies, and a corresponding software algorithm is built. The ground stress test method for aperture distortion optical microscopy measurement solves main technical problems in ground stress tests of deep holes and ultra-deep holes, the ground stress test technology has ground-breaking substantial progress, and has remarkable scientific significance and economical and practical value.

The invention discloses an optical microscope geostress measurement device based on the aperture deformation principle. The optical microscope geostress measurement device comprises a multi-contact-probe measurement component and an optical microscope imaging component; a plurality of sets of contact probes are installed in the multi-contact-probe measurement component in a paired mode, a contact of each contact probe is in contact with the hole wall of a drilled hole to sense aperture changes, and probe tips of the contact probes are concentrated in a tiny area to be synchronous with the contacts in change. The optical microscope imaging component is a sealing barrel with a window and a light source window, and a camera, a microscope lens, a digital compass and an annular light source are located in the optical microscope imaging component. The multi-contact-probe measurement component and the optical microscope imaging component are connected together through a screw; in addition, the microscope lens is aligned with the tiny area containing the tip ends of the contact probes through the window. In brief, the geostress measurement device using the multi-contact-probe aperture deformation sensing structure and the optical microscope measurement technology is provided, and the synchronous multi-group testing capacity is achieved. The optical microscope geostress measurement device is ingenious in design, premise in conception, simple in structure and easy to implement.

The invention discloses a method for testing an optical module, which includes the following steps: performing at least one test item on at least one optical module to be tested with a unique serial number under a plurality of different ambient temperatures; The serial number of the optical module to be tested is associated with the test data of each test item and stored in the local database in the form of an index table. The test data of each test item is indexed by the serial number of the optical module to be tested. The optical module to be tested The serial number of the module is indexed by the ambient temperature; when the test is interrupted and the test is retested, it is determined according to the index table stored in the local database which optical modules to be tested have not completed all the test items at each The light metering module continues testing. The method of the invention does not need to retest the optical modules that have completed all tests, avoids repeated testing, and improves testing efficiency.
