Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred examples.
[0030] The method for determining the parallelism of the optical axes of the continuous zoom TV in this embodiment includes: a collimator 1 , a display 2 , an electric cross generator 3 , an adjustable platform 5 and a square tube front mirror 6 .
[0031] The collimator 1 provides parallel light with a cross reticle; the display 2 is a full-field display capable of displaying the cross reticle image received by the continuous zoom TV 4 and the electric cross image of the continuous zoom TV 4; The cross generator 3 can calibrate the coordinate position of the zoom axis on the display; the adjustable platform 5 is used to place the continuous zoom TV 4 and the square tube front mirror 6, and can adjust the spatial position at the same time; the square tube front mirror 6 serves as a continuous zoom The reference datum of the TV 4 is plac...
