摘要:
An image of a color misregistration detection pattern is formed, and the amount of color misregistration is detected by reading of the pattern image. The amount of color misregistration detected by a detecting unit and the delay time from the time when image data is requested to the time when the image data is output are stored. The color misregistration is corrected based on the stored delay time and amount of color misregistration.

A triple view imaging apparatus is provided for measuring quantitative distribution of material or property in a sample. In the triple view imaging apparatus, an optical system receives an original optical image of the sample, separates the original optical image into at least two secondary optical images having different optical properties from one another, and projects the at least two secondary optical images into a single view angle. A single video camera simultaneously picks up the thus projected plurality of secondary optical images as a single composite image and produces image signals representing the light intensities of the plurality of secondary optical images. An image processor receives the image signals and processes the image signals to obtain final image signals representing a relationship between the image signals for respective ones of the plurality of secondary optical images. An image display receives the calculated final image signals and displays a tertiary optical image based on the calculated final image signals which defines quantitative distribution of material or property in the sample.

A plasma etching apparatus for a semiconductor wafer generates plasma in a plasma generation space between a susceptor and a showerhead. A shield member is detachably disposed inside the sidewall of a process chamber to prevent reaction products from sticking to the sidewall. A window device is arranged to lead plasma light emitted from plasma out of the process chamber. The window device includes a quartz window plate airtightly attached to the sidewall of the process chamber. The window device also includes an aluminum light guide having a number of capillary through holes for guiding the plasma light to the window plate, and a sapphire cover plate disposed between the window plate and the light guide and covering the openings of the through holes. The light guide and the cover plate are attached to the shield member.

The image forming apparatus includes a BG exposure clock output section 305 which outputs a BG exposure clock f1 that slightly emits light from a laser for BG exposure toward a non-toner image forming region on a photosensitive drum 222 and a laser control section 308 which controls the laser so as to slightly emit light for BG exposure based on the BG exposure clock f1 output from the BG exposure clock output section 305. The BG exposure clock output section 305 outputs a clock for BG exposure with a frequency diffused in the range from f1min to f1max.
