Popis: A cube-corner is employed as a photoelectric autocollimator's reflector to extend the angle measurement range and the corresponding algorithms are deduced. Experimental investigations reveal that the measurement range is extended from 1.2° to 12° without enlarging the objective lens's aperture. The accuracy is better than 35" when the deflection is less than 8°.
