Image recording apparatus using the grating light valve |
摘要 |
An optical head 1 of an image recording apparatus 10 is provided with a light-source water-cooling jacket 41 for cooling a light source 11 and a device water-cooling jacket 42 for cooling the Grating Light Valve 12 and a light-shield water-cooling jacket 43. The optical head 10 is also provided with a mirror 31 for reflecting a light form the light source 11 in a non-recording status and mirrors 32, 33 for reflecting non-signal light beams from the light valve 12, and the lights from these mirrors are directed to the light-shield water-cooling jacket 43. Further, a refrigerant from a chiller unit goes through the light-source water-cooling jacket 41, the device water-cooling jacket 42 and the light-shield water-cooling jacket 43 in this order. With this constitution, it is possible to efficiently cool all the heat sources and in the optical head. <IMAGE> |
