摘要

一种光杂讯消除装置包括第一和第二光滤波器、光电转换器及运算单元,第一和第二光滤波器分别允许应用光信号的波长的光和不同于应用光信号的波长的光通过而产生第一光信号和第二背景光杂讯,第一光信号包括应用光信号及相同于应用光信号的波长的第一背景光杂讯,光电转换器侦测第一光信号与第二背景光杂讯,而进行光电转换产生正比于第一光信号的照度的第一电信号及正比于第二背景光杂讯的照度的第二电信号,运算单元将第一电信号和第二电信号分别根据一第一比例与一第二比例进行调整后,再运算得到正比于应用光信号的照度的输出信号,能消除与该应用光信号波长相同的该第一背景光杂讯。
A light noise eliminating device comprises first and second optical filters, a photoelectric converter and an operation unit. The first and second optical filters allow light in the wavelength of an application optical signal and light whose wavelength different from that of the optical signal to pass respectively so as to generate a first optical signal and second background light noise, the first optical signal comprises the application optical signal and first background light noise whose wavelength is the same with that of the application optical signal, the photoelectric converter detectsthe first optical signal and second background light noise and carries out photovoltaic conversion to generate a first electric signal proportional to the illumination of the first optical signal anda second electric signal proportional to the illumination of the second background light noise, and the operation unit adjusts the first and second electric signals according to first and second proportions respectively, and then obtains an output signal proportional to the illumination of the application optical signal by operation. Thus, the first background light noise in the same wavelength of the application optical signal can be eliminated.
