An investigation of reading thermal images processes by a thermal image receiver made in the image intensifier tube architecture
The results of calculations of electric fields, potentials, and trajectories of photoelectrons calculations of single-channel dual-spectral thermal imager, implemented in the IIT architecture are presented. The values of the optimal potentials on the control electrodes (microchannel plate, reading electrode, and photocathode) that form a picture of the images of objects and ensure the correct reading of the potential relief from the surface of the sensor-converter pyroelectric film of the image thermal receiver under discussion are determined. Keywords: image intensifier tube, spontaneous polarization, a pyroelectric sensor, photocathode, photoelectronic emission, thermal object image receiver, secondary electron emission.
