DEVICE DETERMINING POSITION OF RADIOACTIVE SOURCE IN REAL TIME Russian patent published in 2001 - IPC

FIELD: technical physics, remote real time control over spatial distribution of radioactive objects of low activity. SUBSTANCE: device includes chamber with protective shield, optical shutter, coding mask, CCD matrix, remote control desk of optical shutter, unit of input images from CCD matrix, frame summing unit, decoder, digital processing and image visualization unit. Coding mask is located between optical shutter and CCD matrix that can move relative to coding mask. Information output of CCD matrix is connected to input of unit of input of images whose controlling output is connected to proper input of CCD matrix and whose information output is linked to input of frame summing unit. Input of decoder is connected to output of frame summing unit and its output is linked to digital processing and image visualization unit that is coupled by code wire to unit of input of images. EFFECT: increased aperture ratio and generation of volumetric images of radioactive sources. 2 dwg
