Show Several problems remained. Some were administrative problems such as where to find q personnel to spend more than three man years designi constructing the hardware, and how to persua administration to contribute coveted space near a s host computer. More difficult administrative probler associated with the preparation of a proposal solici rather large research grant. Some problems were design problems such as what type of light sources sh used, what type of one-dimensional scanning technique be employed, and how the scanners should be ar: Others were difficult design questions such as how t an adequate light source sensing system, and how to b safe mechanical system which operates with suf: precision. If a spinning disk is used, can sufficien' speed be attained without exceeding the tensile strel the disk material? If a rotating mirror is USE reflection problems, high angular velocity problel field of vision problems be overcome? In general, electronic system be built which operates satisfactoJ the presence of large electric motors and other elc electronic equipment? Can all parts of the system be r operate together and under computer control? SomE simple theory questions such as how the light sources distinguished from one another, and what existing use approaches and ideas which may be helpful? Othel |
