Spatial distribution of radiation absorption or emission - is determined by measured value signals passed through AD converter to operational amplifier (BE161176)

摘要

The absorption or emission radiation characteristics of a body is measured in a number of directions. The measured values (M1, M2, ... M) are fed to a digital disc register (Sch) incorporating a number of transverse filters. The register is required to have (2n-1) cells, each associated with a number of resistors (R1, R2, ... R2n-1). The outputs of the latter are connected with an operational amplifier (S) which produces modified valves (M1, M2, . . . M ). All the units are actuated by the same triggering pulse signal t. An analogue-digital converter may be used in advance of the register to transmit the measured valves in digital form to the operational amplifier.
