Method for producing picture element groups by means of laser rays in space and on a plane

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus pursuant to FIG.
2 comprises a x-deflection mirror 3 and a y-deflection mirror 4, which has a cutout 11 in the middle.
Part of the image beam reflected by the deflection mirror 4 is reflected by the y-deflection mirror 4 as a main beam 12, while another part of the image beam is reflected by the secondary mirror 14 as a secondary beam 13.
This secondary mirror is swivel-mounted in the rotation axis 15, which in turn rests in a ring 16 that can swivel orthogonally and with which the axis 15 can be turned.
The light beams 12 and 13 run parallel to each other as long as the reflection planes of the mirrors 4 and 14 are aligned parallel to each other.
Any twist of the mirror 14 about the rotation axis 13 or with the ring 16 alters the secondary beam 13, producing an independent picture element on the helix corresponding to its relative position.
Proceeding from small twist increments 15 and 16, this additional picture element lies near the picture element produced by the main beam 12.
Its size depends on the opening of the cutout 11.
This makes it possible to represent line segments of element groups on the helix.
Their direction is determined by the position of the ring 16 and their length is determined by the extent of oscillation amplitude of the mirror 14 about the rotation axis 15.
They can originate in the picture element produced by the main beam 12.
They would thus appear as 3D vectors, similar in appearance to the vapor trails of a jet airplane.
For flight-controllers, they can be seen as representing the speed and direction of an aircraft.
The oscillation of the secondary mirror can and should be constant, but independent of the rotation speed of the helix.
The light flashes for the main beam and secondary beam 13 are identical.
By forgoing any synchronization here, the partial picture elements appear in statistical distribution between the positional limits.
This causes a line element marked by minutely flickering light flashes to appear in addition to the strictly stationary main picture element at the x,y,z position
