Fore-Optics Systems Designed for Electronic Streak Cameras Using Fiber Optics

摘要

We describe the general principles that should be considered in designing a fore-optics system to image signals from optical fibers onto the photocathode of a streak tube. Important design considerations of these systems include lens design (resolution, magnification, relative aperture, field size, and transmission), use of supplementary field lenses, and the configuration of the fiber arrays. We also discuss provisions made in these systems to evaluate all channels of the complete fiber system and to align the fiber-array images on the photocathode. Typical applications of these fore-optics systems include simultaneous filtering of multiple channels of optical signals, reducing the size of the image, or using a streak camera that has a curved front window.
