    • A sensing apparatus includes: a broadband optical source; a first pseudorandom number generator generating a first pseudorandom number code string to modulate the broadband optical source; at least one sensor reflecting an output of the first pseudorandom number generator at a wavelength corresponding to a center wavelength thereof when the output of the first pseudorandom number generator is inputted; a wavelength-time converter converting an output of the sensor by wavelength-time conversion; a second pseudorandom number generator generating a second pseudorandom number code string which is different in frequency from and is the same in bit length and code string as the first pseudorandom number code string; a mixer mixing an output signal of the wavelength-time converter with an output signal of the second pseudorandom number generator; and an integrator integrating an output of the mixer.
    • 感测装置包括:宽带光源; 产生第一伪随机数字码串以调制所述宽带光源的第一伪随机数发生器; 当输入第一伪随机数发生器的输出时,至少一个传感器以与其中心波长相对应的波长反映第一伪随机数发生器的输出; 波长时间转换器,通过波长时间转换转换传感器的输出; 第二伪随机数生成器,生成与所述第一伪随机数代码串相对应的位长度和代码串的频率不同且相同的第二伪随机数代码串; 将波长 - 时间转换器的输出信号与第二伪随机数发生器的输出信号混合的混频器; 以及集成了混频器的输出的积分器。
