Scientific paper

An airborne telescope utilizing a scanning interferometer and video recording system has been used for coronal-emission-line-profile measurements during the total solar eclipses of 1972 and 1973. A 250 mm diameter f/8.0 achromatic doublet refractor served as the objective lens, and a pressure scanned Fabry-Perot interferometer with narrow band transmission filters provided 0.005 nm spectral resolution of the selected emission lines. A variable-gain channel-plate image intensifier, fiber-optically coupled to a Sb2S3 vidicon tube, was adapted for use as a high sensitivity image detector. The vidicon tube was scanned at a rate of 60 fields per second in a 500-line, noninterlaced television format. The composite video signals were recorded on standard video tapes from which they were digitized for subsequent computer processing.
