Pmotoelectric Recorsaing
The possibility of usin; pnotemultialicrs ror absvlote measerement. of
radiant enersy as described tn this report warrants consicerat:co.
tuints of calibration,
relative sinplicity of data reductica,
The cer-
iamewiacs of data,
and the eugse of hendling this type of equipsent in the field are teviting qulities, imleed.
11.8.2
Diaseter versus Tix.
The use of high-speed streak cazerus with lenseS is recugemed to record
high-resolution diameter versus time.
ft/sec,
A writing speed of 150 ft/sec to 200
in combination with a narrow stilt (U0.Q8 iach), could
cbesin cime reso-
lution of the order of 1 ysec.
11.6.3
Motion Picture Coverage
The use of several high-speed 35-mm ovtion picture cameras in the ranie
of 1000 to 2000 trames/see is suggested for mre adequate early-time color
photograpiia.
Instrumentation should continue through 3 range of cameras lo
equiarzent
of the “pulse” txpe which could record extrene late-tise P phenomna.
