| Abstract: | A PEV polarizing sequence with fixed target voltage is given. A distinctive automatic polarizing system for use in the PEV infrared television camera is proposed. A voltage comparator isused as the timer instead of the monostable trigger or counter circuit normally used in such a system.The system has been used in a variety of PEV infrared television cameras developed by HUST. Practice has proved that the system is simple in structure, easy to select circuit parameters and to adjust,stable in operation and fairly good in anti-interference. |
