Title:
感光性表面に画像を形成する装置
Document Type and Number:
Japanese Patent JP5746512
Kind Code:
B2
Abstract:
Two integrated multi-beam sources (52,54) are positioned and disposed such that each emits light toward an optical splitter (70,74). The emitted light is polarized such that the splitter brings the optical paths of the two integrated multi-beam sources generally parallel to one another such that the optical system aperture throughput for the two integrated multi-beam sources is roughly the same as for a single integrated multi-beam source. The splitter (70,74) may be such that a portion of the optical energy from each source is directed into an imaging path and a portion of the optical energy is directed toward one or more non-polarizing splitters and optical sensors for, inter alia, controlling the output of the sources. In various embodiments, the number of splitters, and hence the extent of optical loss, may be reduced by use of a combined polarized and non-polarized splitter, dual polarized splitters, and time-sequenced beam generation and monitoring.
