This project covers the installation of encoders and associated
electronics along with the improved alignment and higher precision
mechanical components required to incor orate a comparator mensuration
capability in the Point Transfer Device now
under contract.

II. Objectives

25X1
This Development will result in thel Point Transfer Device
having broad additional capabilities as a highly versatile stereo-comparator
approaching accuracies of 3 microns over distances under 1 mm. and 4 microns
over distances up to 20 mm. The lencoders provide a least count of
1 micron. This accuracy combined with the standard ultra-high resolution
optics and the capability to accommodate roll film are expected to assist
TID considerably in their efforts to solve current operational mens
problems. The associated electronics
are to take the output signal from the lencoders and feed the data
on-line to the computer on operator comman .
III. Background
Changing operational requirements and changes in mensuration philosophy
within TAB/TID have made it expedient to incorporate a precision comparator
capability into the Point Transfer Device presently being
fabricated at the vendor's lant.The rugged base casting and precision
screws and ways chosen are intrinsically well suited for
comparator applications. Ideally, an ultra-high precision comparator should,
from its conception, be designed from "the-ground-up" for that purpose alone;
however, there is an urgent requirement for a stereo-comparator, with high
resolution optics, capable of effectively utilizing film in roll form. R & D
lead times do not permit a new development with an early enough delivery date
to meet current requirements; therefore, it is deemed expedient to incorporate
comparator capabilities into thel -]Point Transfer Device,

TV. Technical Specification
The ^Point Transfer Device will be modified to incorporate an Automatic
Comparator - Mensuration capebi.li.ty~ This system will, employ four (4)
Dynamic Research 1 1 encoders directly attached to 22 mm pitch, precision
ground, ball lead screws on all. four (4) axes. These encoders provide 2,500
(-aunts -per revolution, or a one micron bit size (least, count)
The majority of the cost of the proposal is for modifying
the castings and other components to accommodate encoders and for the
ultra,-preecise alignment of the ways and screws to obtain the specified
accuracies.
All counters, di.spla; s and readout recording equipment will be provided
