“…The method of optical geometry also tends to result in lowaccuracy measurement due to its measuring principle and the sensitivity to the beam drift caused by air disturbance and laser source. With this method, various reflective components, including a mirror [7,8], corner cube retroreflector [9][10][11], rightangle prism [12], and grating [13], are installed in the objects to sense the roll displacement. The basic work principle is same or similar to the principle of an autocollimator.…”

An approach to precise measurement of small roll angle based on digital speckle pattern interferometry (DSPI) is introduced. A simple relationship between the roll angle and interferometric phase distribution is established by analyzing the mechanism of fringe formation in the process of roll detection using a dual-beam DSPI, and reasonable approximate processing. The presented method enjoys some important advantages, such as being free of a cooperative target and a very high measurement resolution. In our experiments, a measurement resolution of 1 µrad, which can compete with the best resolution of the existing methods, is achieved. Theoretically, the measurement resolution can even be improved to tens of nano-radians at the cost of increasing the size of the measuring device. The performance of the method is also demonstrated by a comparison experiment.

“…Tan's group [8] used a system which could simultaneously measure three degree of freedom (3-DOF) and compensation errors via this method. Kuang's group used the same method for some small angular displacements [9] and roll angles [10]. In our previous work, we have combined the common-path compensation method with a 6-DOF system in order to realized compensations for straightness errors, yaws, pitches and rolls.…”

The laser beam drift is a main factor that influences laser collimation measurement accuracies. In such measurements, the common-path compensation method is an efficient way to eliminate errors which are normally produced by the laser beam drift. Based on our current common-path compensation system, compensations for the laser beam drift were studied by different laser beam radii and detectors. The measurements have shown that the compensation effect for 3 mm beam radius is better than the ones of 1.5 mm and 4.0 mm beam radii. Based on this, the ratio between the 3 mm beam radius and the total area of the quadrant detector, which is 36%, has indicated the best compensation effect.
