摘要： An inexpensive and highly productive exposure device for directly scanning and exposing a photosensitive material sensitive to at least a UV region, based on digital data. As a motor controller moves an exposure head at a fixed speed in Y direction, image data is read one line of image data, each GLV element of a light modulator array is switched on/off by the read image data, and laser light from a high power light source of the exposure head is switched on/off. A UV-sensitive object to be exposed is exposed in X direction in a number of pixel units that substantially corresponds to the number of the GLV elements. The image data is scanned and exposed by one line in Y direction (main-scan). The motor controller moves a flat stage by one step in X direction (sub-scan). The object to be exposed is imagewise-exposed by repeating such scans.

摘要： An exposure method that can conduct digital exposure with high precision and with a high light-use efficiency using evanescent light. Light that is modulated by a DMD and condensed by a microlens array is incident at corresponding optical fiber cores arranged in a matrix in an evanescent array head, and is guided through the insides of the optical fibers. Because the light condensed by the microlens array is incident at the optical fiber cores corresponding to the microlenses, the light can be efficiently incident. Evanescent light leaks out from micro-openings formed in emission-side end portions of the optical fibers, and a photosensitive material is exposed by this evanescent light.
