An optical pattern generator uses a single rotating component (Fig. 1A, 9). The rotating component includes a number of deflection sectors (8A, 8B, 8C, etc.). Each sector deflects an incident optical beam by a substantially constant angular amount although this amount may vary from one sector to the next. The rotating component may be combined with an imaging lens group (Fig. 2A, 19) that produces, for example, image points, spots, lines displaced along a line locus. |
