| 摘要 | PURPOSE:To detect more exactly the life of an optical information source by increasing the time information on the emission time of the optical information source stored in a measuring storage means by a correction means when the output of the optical information source is high and decreasing said information when the output is low. CONSTITUTION:A clock pulse generator 3' such as crystal oscillator is connected to a counter 3 which counts the number of clock pulses as the time information received during the duration period of the emission signal of a laser 2. A memory 4 which adds and stores successively the output from the counter 3 is connected to a comparator 5 as a comparing means. The measuring storage means 4' is constituted with such counter 3, the clock pulse generating means 3' and the memory 4. The comparator 5, which is connected to a controller 6 as the correction means, compares the prescribed level set in accordance with the average service life of the laser and the emission time of the laser 2 stored in the memory 4 and outputs a signal Su to announce the termination of the service life of the laser. |
| 其他摘要 | 用途：当光学信息源的输出高并且减小所述光学信息源的输出时，通过校正装置增加存储在测量存储装置中的光学信息源的发射时间的时间信息，以更精确地检测光学信息源的寿命。输出低时的信息。组成：一个时钟脉冲发生器3'，如晶体振荡器连接到计数器3，计数器3计数时钟脉冲的数量作为在激光器2的发射信号的持续时间段期间接收的时间信息。存储器4，其添加和存储连续地，来自计数器3的输出连接到作为比较装置的比较器5。测量存储装置4'由这样的计数器3，时钟脉冲发生装置3'和存储器4构成。比较器5连接到作为校正装置的控制器6，比较根据设定的规定电平。激光器的平均使用寿命和存储在存储器4中的激光器2的发射时间输出信号Su以宣告激光器的使用寿命终止。 |
