Resolution may be improved by (1) raising the photocathode voltage, (2) separating the exposure and scanning operations in time so as to minimize the effect of leakage of scan fields into image section, (3) cooling the target and (4) scanning slowly without reduction of bandwidth. When operated as suggested with highlights near the “knee,” the 3-in. image orthicon has an amplitude response of 50% at 900 TV-lines and a limiting resolution of about 1500 TV-lines. With increased illumination a limiting resolution of 3000 TV-lines (60 line-pairs/mm) is attained. Maximum resolution is set by capacitive coupling between elements at the target. Response to stellar or point source images is discussed. Measurement techniques and the sine-wave response of test lenses are given.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J06135.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "articleType": "research-article", "articleType$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J06135.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ "William C.
