Coaxial deviation measurement of lasers with different wavelengths

Facing the dichroic beam combiner, taking the reflection optical lever angle as the observation route, it is planned to output the time-sharing center difference and angle candidate. The page is for project evaluation and does not mean that the development has been completed or has been accepted on site.

Current capabilities and capabilities to be supplemented

Partially reusable

Requires calibration, synchronization or integration

The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.

Gaps in this scenario:Optical lever geometry, reflection double angle relationship and incident point movement compensation are required; mirror angle and target translation must be separated. Each wavelength has different focal lengths and sensor responses. The installation output must correspond to the installation reference and operating wavelength.

Route-level gaps:Optical lever geometry, reflection double angle relationship and incident point movement compensation are required; mirror angle and target translation must be separated

"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.

Verification methods and acceptance prerequisites

Use an independent angle stage/autocollimator to conduct bidirectional and multi-attitude tests, and report the angle error and return difference. Repeat clamping and compare with autocollimator or mechanical datum
