- Summary
- This work examines the human color vision mechanism in light of Dr. E. H. Land's two-color experiments on color vision. The problem of color perception in machines is looked into. Some of the two-color experiments are described. But the main emphasis has been on the building of a two-color television display system based on the two-color projection experiments. The Penetron Electronic Color System (PENTECOST) is a two-primary color television system intended to examine the scope and the limitations of using the Land two-primary scheme for high resolution color information displays. It employs a penetration type cathode ray tube (Penetron) having red and white layers of phosphors that are sequentially excited every alternate field to display the red and green record of a scene taken synchronously through the red -green color filter-wheel. The Penetron tube as a color displays tube is evaluated and the different switching and registration circuits are described. The camera system with the lead-oxide vidicon (Plumbicon) pick-up tube, the color filter-wheel, and the associated synchronizing circuits are also described. The use of an electronically controlled solid state filter like Gadolinium Molybdate instead of the color wheel is considered.
