摘要
An optical bandpass separator and systems based thereon split target and continuum band signals. The separator includes a first optical path for selectively transmitting a target band signal. The first optical path includes a first prism and a first bandpass filter. The separator includes a second optical path non-overlapping with the first optical path for transmitting a continuum band signal. The second optical path includes a second prism and a second bandpass filter. The spacing of the first and second optical paths allows the simultaneous and separate imaging or detection of the target band signal and the continuum band signal using a single imager or detector.
