A trace T is formed on a moving strip SP of paper sensitive to ultra-violet light by a beam from a source S of ultra-violet light directed by a system of lenses L1, L2 and L3, fixed mirrors M1, M2 and M3 and the mirrors of two galvanometers G1, G2, the electrical signal being fed to G2 and the further modulating electrical signal to G1 or G2. The signal to G2 may be of constant amplitude and frequency or it may be modulated with information to be recorded in the form of a trace and the further signal applied to G1 to record further information by varying the intensity of the trace between light and dark limits or between a particular intensity and no mark to form a dashed line. If the signal to G2 has a varying frequency this can be used to modulate the intensity. A coded message e.g. in morse represented by the signal to G1 can be recorded and a picture can be reproduced by making the frequency of the transverse signal sufficiently high relative to the speed of the strip to form a raster. Galvanometer G1 may be replaced by a Kerr cell or a mechanical shutter for modulating the scanning light spot.
