with yellow reflexed paint and the objects were lit 
by halogens. This method of imaging allows to determine 
the successive phases of the changes of the object by 
time - parallaxes method without a necessity of eli 
mination of differences in exterior orientation of 
photographs. The endurance examination of concrete 
samples on account of small shape /40 x 10 x 2 cm/ 
and high accuraccy of measurement /ca - 0.01 mm/ 
reguired the taking of photographs in 1:1 scale. For 
this purpose, the long focus length camera / f = 300 
mm/ had.been constructed. The imaging of .successive 
states of stretched samples allowed to determine 
their deformations and local breaks could be found. 
3 . Final conclusions 
On the base of the above presented experiments it 
may be ascertained that applying of photogrammetry in 
fields of industry is technically and economically justified. 
As evidence of this statement, it is enought to men 
tion the fact that many branches of industry turn to 
scientific photogrammetric departments with requests 
for help in solving a number of difficult tasks and 
the progess in the already existing methods and search 
for new photogrammetric procedures are greatly needed 
Besides, some photogrammetric technology elaborated 
in Inst it ut of Photogrammetry and Cartography of Warsaw 
Technical University are used in Photogrammetric 
Laboratoryes of the Eneterprise of Geodesy. 
Irrespective of the type of the measured objects, 
however, photogrammetric methods prove superior to 
other approaches since they are characterized by the 
following features: 
- the possibility of recording of objects which are 
impervious to other methods of measurement, 
- the possibility of examination of the processes 
arbitrarily speedy, 
- the possibility of simultaneous recording of an 
arbitrarily large number of points on the photograph
