b. Clear objectives will be formulated. 
c. Attention will be focused on those parameters upon which optimization 
depends. 
d. Exposure will be made of overly stringent, overly sophisticated, in 
adequate and/or unrealistic design requirements. 
e. Generation of ideas for new equipment (considered from an integrated 
systems and compatibility standpoint) will be made. 
f. Distinction will be made of those factors which are important, and, 
those which are not, in order to reorient development effort. 
g. Determination will be made of more effective ways to use equipment. 
h. Development will be made of performance standards for new equip 
ment, products, techniques, and materials. 
i. Attention will be focused on areas where a new demand for equipment, 
products, techniques, and materials might exist or an improvement might be 
required. 
SECTION II. CHARACTERISTICS OF EQUIPMENT 
BAUSCH AND LOMB COMPANY. 
The Bausch and Lomb (B&L) Company, Rochester, New York, USA, has 
developed a number of photogrammetric instruments in the period 1964-68 in 
cluding a Short Range Photogrammetric System for Dental Surgery, a Digital 
Linear Measuring System (DIG) for Comparators, the Terrain Profile Recorder 
(TPR) Image Point Transfer Instrument, the Variscale Stereo Point Marking 
Instrument, and two scale-type linear measuring instruments, the Dual Power 
Measuring Macroscope, and the Projected Scale Micrometer. Details regarding 
some of them follow: 
a. The Terrain Profile Recorder (TPR) Image Point Transfer Instrument 
was developed to transfer rapidly image information from small-format TPR 
Spotting camera photography to larger format cartographic photography. It is 
used mainly in the application of TPR vertical control data to aerial triangulation 
procedure in universal stereophotogrammetric instruments. The device consists 
of diapositive and film holders, a scanning system, a binocular-optical viewing 
system, and a point marking system. The left optical train of the view-system 
has a continuously variable magnification and the right optical train has a fixed 
magnification. Transfer of the TPR radar beam centers (nadir points) to the 
cartographic photography is accomplished with a relatively high accuracy. 
Parallax is eliminated by means of the floating mark principle. A dot surrounded 
by a flagging circle is molded into the film emulsion at the time of point marking. 
For this purpose a capaciter discharge is used for instantaneously heating a
