The readout scanners utilized onboard the Lunar Orbiter spacecraft employed a phosphor-covered anode bombarded by an electron beam to focus a spot of light on 70mm film developed onboard the spacecraft. This light was modulated by the density of the image and read by a photomultiplier tube. Each individual pass of this scanning procedure across the 70mm film produced a thin strip of a larger image, referred to as a &#8220;framelet&#8221;. The product of the spacecraft&#8217;s readout system was a video waveform that was modulated and transmitted to three DSIF stations and recorded onto 2-inch magnetic tape via Ampex FR-900 data recorders. This document discusses the process by which these video signals were converted into digital images.&#8221;<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Click on image for PDF version of poster Poster presented at the 42nd Lunar and Planetary Science Conference by A.
