Image Quality and Performance of the LSST Camera
Abstract
The LSST camera, which will be the largest digital camera built to date, presents a number of novel challenges. The field of view will be 3.5 degrees in diameter and will be sampled by a 3.2 billion pixel array of sensors to be read-out in under 2 seconds, which leads to demanding constraints on the sensor architecture and read-out electronics. The camera also incorporates three large refractive lenses, an array of five wide-band large filters mounted on a carousel, and a mechanical shutter. Given the fast optical beam (f/1.2) and tight tolerances for image quality and throughput specifications, the requirements on the optical design, assembly and alignment, and contamination control of the optical elements and focal plane are crucial. We present an overview of the LSST camera, with an emphasis on models of camera image quality and throughput performance that are characterized by various analysis packages and design considerations.
