Abstract: A method of measuring scanning characteristics of an optical scanning apparatus allows measurement of scanning characteristics of an actuator. The method includes bringing a tip of the optical scanning apparatus and a chart for measuring scanning characteristics closer together and irradiating illumination light with the actuator in a non-driven state, separating the tip and the chart for measuring scanning characteristics by a predetermined distance while maintaining the relative orientations thereof, and adjusting a drive signal of the actuator so that a scanning area of the illumination light on the chart for measuring scanning characteristics can form a desired shape. At least one of an angle of deviation and a viewing angle is measured using an irradiation position of the illumination light on the chart for measuring scanning characteristics.
