Abstract
Some implementations include an opto-mechanical assembly of a microscope system for testing an end face of an optical fiber. The opto-mechanical assembly may include an imaging device configured to capture an image of an end face of an optical fiber and a focus assembly comprising a system of lenses configured to focus the image of the end face of the optical fiber for capture by the imaging device; and at least one focus position encoder associated with the focus assembly and configured to determine at least one focus position measurement associated with a position of at least one lens of the system of lenses. The device may use the at least one focus position measurement to determine a magnification associated with the focus assembly.
Claims20
A device, comprising:
- an opto-mechanical assembly comprising an imaging device configured to capture an image of an end face of an optical fiber and a focus assembly comprising a system of lenses configured to focus the image of the end face of the optical fiber for capture by the imaging device;
- at least one focus position encoder disposed in the opto-mechanical assembly and configured to determine at least one focus position measurement associated with a position of at least one lens of the system of lenses;
- one or more memories disposed in the opto-mechanical assembly;
- and
- one or more processors, disposed in the opto-mechanical assembly and coupled to the one or more memories, configured to:
- obtain, from the at least one focus position encoder, the at least one focus position measurement;
- determine, based on the at least one focus position measurement, a magnification value associated with the focus assembly;
- perform, based on the magnification value, a test to inspect an image of an end face of an optical fiber for compliance with a set of criteria related to a condition of the end face of the optical fiber, wherein at least one testing parameter is based on the magnification value;
- and
- output a result of the test that indicates a compliance status associated with the set of criteria.
