The invention relates to a projector for simulating a scene image, especially the view from an aeroplane, by means of calligraphic lights. A control device that is connected to a modulator of the projector generates signals for the scene image and signals for the calligraphic lights. The invention is characterised in that the projector (100) comprises two light sources (10, 10'). Each of said light sources produces an intensity-modulated and colour-modulated collinear R-G-B light bundle ( PHI A(t)) and ( PHI B(t)) respectively in a determined time ratio in relation to the remaining light source and by means of the signals (A, B) of the control device (60). Modulators (2) are controlled in the first light source (10) by means of a first signal (A) in such a way that a first R-G-B light bundle ( PHI A(t)) contains the optical information for the scene image (17) and the optical information for the calligraphic lights and modulators (2') are controlled in the second light source (10') by means of a second signal (B) in such a way that a second R-G-B light bundle ( PHI B(t)) contains only the optical information for the calligraphic lights. A means (20) for combining beams is also provided. The first and the second R-G-B light bundle ( PHI A(t)) and ( PHI B(t)) radiate from said means in a spatially combined manner and are simultaneously projected onto the projection surface by means of one deflection device (11, 12; 18) only and in such a way that the two R-G-B light bundles ( PHI A(t)) and ( PHI B(t)) overlap in the image points in an intensity-wise manner, whereby the calligraphic lights are represented in said points and the deflection device comprises two axes.
