1. A method of operating a projector, comprising:
- concurrently directing at least first and second narrowband beams of light, respectively of different wavelengths, onto a modulator respectively at first and second angles of incidence;
wherein said first and second angles of incidence are selected so that a single size of a gap between total and partial reflectors of the modulator produces substantially a same reflective or absorptive state for the first and second beams.

12. A projector, comprising:
- a light source configured to direct first and second beams of light, respectively at different wavelengths, onto a modulator at respectively first and second angles of incidence the modulator comprising;
a partial reflector;
a total reflector; and
a selectively adjustable gap interposed between the partial and total reflectors;
wherein the first and second angles of incidence are selected so that a selected first size of the gap produces substantially a same reflective state for the first and second beams and a selected second size of the gap produces substantially a same absorptive state for the first and second beams. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
