“…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). Moreover, it is insensitive to roll angle [6][7][8][9]. The sensitivity is results from the focal length of the collimating lens and the field of view of the 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.

“…Este estudio permitió obtener el cálculo de incertidumbre del nuevo instrumento (Bergues et al, 2018). Finalmente, se realizó la calibración del dispositivo con el Patrón Nacional de Ángulo del Instituto Nacional de Metrología de Argentina (INTI) y se estudió la performance del instrumento a partir de los resultados de la calibración (Bergues et al, 2020).…”

En este trabajo se presenta la interfaz gráfica de usuario y se explica el modelo de detección de líneas diseñado en Python para la misma. Luego de los resultados de la calibración del instrumento electrónico se procedió a crear la interfaz gráfica de usuario en python en base al prototipo de la GUI construida en Matlab para lo cual se tuvo que escribir el algoritmo de detección en el mismo lenguaje. El instrumento electrónico está construido con un autocolimador analógico comercial, Nikon 6D, y una interfaz visual ad hoc.

An influence model of collimating lens aberrations in autocollimation system based on the ray-tracing method is established. With the ray-tracing method, this model can accurately compute the direction and position of each light ray passing through the collimating lens in autocollimation system, thereby obtaining the light-spot position of each light ray on the sensor, and determining the systematic error caused by aberrations. Eventually, this model serves to compensate the measurement error of autocollimators and improve the accuracy. Simulations and experiments demonstrate that the influence quantity of angular measurement value due to aberrations reaches 0.74 arcsec within the range of ±500 arcsec. And in a large-aberration situation, the measurement accuracy is promoted to 3.33 arcsec, approximately 5 times higher than that without compensation.
