Title: Driving method for pyroelectric type heat image pick-up tube
Inventor: TOMII KAORU
IPC: H04N5/33
Filed: 1981-11-11
Abstract: PURPOSE:To obtain a constant pedestal potential by performing the generation of the pedestal potential and a reading of heat image pattern charge for every field in an effective scanning time. CONSTITUTION:A signal (a) is applied to the cathode of a pyroelectric type heat image pickup tube 2, and a signal (b) is applied to the electron beam control electrode. Namely, in the 1st field, the cathode is held at -VKP while the control electrode is held at -VGIP, and thus a high current is flowed to the target 3 to emit secondary electron, generating a pedestal potential. In the 2nd field, the cathode is held at 0V while the control electrode is held at -VGI, and thus a prescribed electron beam is flowed to read charge of a heat image pattern appearing on the target surface. In this case, blanking pulses 33 are applied as the signal (b). Consequently, the scanning speed of the beam is constant within an effective scanning time, so a specified pedestal potential is obtained.
