Description

Technical Field

[0001] This utility model belongs to the field of zero-position testing technology for optoelectronic products, and specifically relates to a zero-position testing adjustment fixture bracket for optoelectronic products. Background Technology

[0002] Zero-position calibration is a crucial control step for effective target tracking in optoelectronic products, ensuring a high degree of alignment between the product's optical axis and rotation axis. Inaccurate zero-position calibration will prevent the accurate measurement of the product's actual deflection angle, directly affecting the equipment's flight trajectory. This leads to inaccurate control signals manipulating actuators, hindering effective target tracking in combat and potentially causing friendly fire incidents. Therefore, zero-position calibration is a vital step in the testing of optoelectronic product systems.

[0003] Zero-position calibration testing primarily involves rotating the product to calculate the alignment between the target center of the target simulator and the crosshair, and then using software to compensate for and calibrate the pitch and azimuth errors of the product. Existing tooling adjustments have certain limitations, including insufficient rotation range of the target simulator and low positioning accuracy. Utility Model Content
