The lamp 1 is fastened by a lamp retaining ring 2 and the fan 5 is fastened by a blast fan retaining ring 6. The lamp house 8 is mounted to an engine frame 20 by means of a lamp house band 15. Light emitted from the lamp 1 passes through an optical fiber 11 and the light signal formed by a liquid crystal micro optical shutter array 17 is imaged on the surface of a photosensitive body 21 by a near parabolic fiber array 16.</p> |
