The invention provides a color wheel for Micro-Device (MD) projection display. The color wheel of the invention includes a color filter with different colors divided on the circumference thereof, a driving motor rotating a rotor with the color filter assembled thereinto, and a filter adhesion layer fixing the color filter to the carrier by an adhesive applied on the overlapping region of the carrier and the color filter. The color wheel also includes a holder having a fixing part to maintain compressive stress offsetting tensile stress generated at the filter adhesion layer. The invention minimizes tensile stress at the adhesion part for fixing the color filter, increasing the adhesive force between the adherent and the adhesive, thereby allowing firm fixing of the color filter to the driving motor without using an adhesive.

Disclosed herein are a CDMA optical system and encoder and decoder included therein. Time domain encoding means creates a time domain code having a sequence according to inputted data bits or a complementary code which is complementary to the time domain code. An optical modulation means selectively outputs lights, in which the lights are incident upon the optical modulation means from the outside, to two output leads, respectively, according to chip bits of the time domain code or the complementary code. A wavelength domain encoding means encodes the light outputted from a first output lead of the optical modulation means to a wavelength domain sequence (two dimensional code), transmits the wavelength code to the base station, encodes the light outputted from a second output lead to a complementary sequence of the wavelength domain sequence, and transmits the complementary code of the two dimensional code to the base station.
