METHODS OF WIDE FIELD IMAGE ORTHICON PHOTOGRAPHY AND THEORETICAL INVESTIGATIONS WITH APPLICATION TO THE AIRBORNE ASTROGRAPHIC CAMERA SYSTEM.
Abstract
The report covers the following topics: Image orthicon (1) description of the modified UVR 300 image orthicon camera system and some preliminary results obtained with this instrument at Kirtland; (2) discussion of initial results obtained at Dearborn Observatory using the Dearborn image orthicon camera and an Aerojet Delft Rayxar lens (105 mm focal length, f ratio 0.75) furnished by AFSWC; (3) star identification on image orthicon photographs; (4) Modified UVR 300 system-Rayxar 150 f0.75 lens limiting magnitude; (5) comparison of sensitivity of an S-10 I.O. and RXP film; (6) evaluation of image orthicon plate reduction accuracy, with both the Kirtland and the Dearborn instruments; (7) low dispersion objective grating spectroscopy with an image orthicon camera system; (8) applications of composite photography to image orthicon observations; (9) a rocketborne solution to the problem of daytime observation of artificial earth satellites; (10) a method for determining positions of objects observed with long focal length, narrow field instruments; Investigations related to the airborne astrographic camera system (1) Off axis camera correlation; (2) A restricted single aircraft solution; (3) Astronomical refraction and rocket refraction in the airborne case; (4) Determination of lens distortion as a means of reducing error in observations with a limited number of stars; (5) identification of a problem area in AACS data reduction and a proposed solution; (6) analyses of Airborne Astrographic Camera System observational results in terms of system accuracy.
