摘要： Structure for the all-around display of a flat image over an angle of 360.degree.. The image should be visible with a continuous luminous intensity, regardless of the rotary speed. According to the invention, the maximum variation of the luminous flux from the light source--as a function of the rotary speed--must not reach a degree which is detectable by the human visual apparatus. Advantage is taken of the sluggishness of the human visual apparatus if, during each complete revolution of the image carrier through 360.degree., the total time of all bright phases is at least 30%, preferably at least 50%, in particular at least 70%, of the time of a revolution of the image carrier, and/or if the frequency of the bright phases is at least 200 Hz, the bright phases preferably emitting at least 75%, in particular at least 90%, of the maximum luminous intensity.
