Optical axis detection is a testing method used to detect the axial position and positioning accuracy of optical components. The following is the principle of the optical axis AA detection equipment:
1. Basic principle: The optical axis AA detection device utilizes optical principles to determine the axial position and positioning accuracy of the component by measuring the position and direction of the incident beam passing through the tested component and the outgoing beam.
2. Measurement optical path: Optical axis AA detection equipment usually consists of a light source, beam splitting system, tested components, detection system, and data processing system. The light source emits a beam of light, which is divided into multiple beams through a beam splitting system. One beam intersects with the tested component, passes through the component, and forms an outgoing beam, which is then received by the detection system.
3. Reception and measurement: Detection systems typically use optical detectors (such as photoresistors, photodiodes, etc.) to receive outgoing light beams and convert the received optical signals into electrical signals. Determine the axial position and positioning accuracy of the tested component by measuring parameters such as the strength, position, and direction of the electrical signal.
4. Data processing: The detection system amplifies, filters, and performs numerical calculations on the received optical signal to obtain relevant data on the axial position and positioning accuracy of the tested component. These data can be used to determine the manufacturing quality of components, refer to the assembly process, or adjust the position of components.
5. Result analysis: Based on the measurement data, it is possible to evaluate whether the axial position and positioning accuracy of the tested component meet the specified requirements. If it does not meet the requirements, adjustments, reprocessing, or other measures can be taken to improve the axial positioning of the components.
The principle of optical axis AA detection equipment is based on optical measurement and signal processing technology, which can quickly and accurately evaluate the axial position and positioning accuracy of optical components. It is widely used in optical manufacturing, optical testing, and assembly fields.
