“…Autocollimators (ACs) are angle-measurement instruments for achieving high accuracy, high angular sensitivity, fast, and non-contact measurement, which are extensively used in the fields of industrial production, national defense technology, and scientific research [1][2][3][4][5]. For the classical ACs, only pitch and yaw can be measured based on the collimation of a light beam, which reflected by a mirror and focused on a 2D position sensitive detector (PSD).…”

Autocollimators (ACs) are primarily used for two-dimension measurement with small angle. A three-dimensional AC (3D-AC) with a large measurement range and capable of 3D angle measurement is proposed based on a modified cube corner reflector (MCCR). The MCCR structure is designed by establishing the space coordinate vector relation model between AC and the reflectors with the rotation relation of Euler space. A 3D-AC angle measurement equation for MCCR dimension angle recognition is established. Experiments demonstrate that the proposed 3D-AC model can be used for 3D measurement. The measurement range of 3D-AC is 10°, and the uncertainty values for the one-dimensional and combined angle measurements are (57.10″, 55.25″, 40.43″) and (394.16″, 455.36″, 319.57″), respectively.
