芯片大小的光谱仪是由一个线性可变带通滤波器和一个cmos摄像机相结合实现的。滤光器将入射光的光谱信息转换为空间相关信号，由相机进行分析。在光谱仪上集成了一个流体平台，用于分析来自运动物体的荧光。目标在反共振波导内被连续激发，当目标穿过探测区域时，其荧光光谱被记录下来。
A chip-size spectrometer is realized by combining a linear variable band-pass filter with a CMOS camera. The filter converts the spectral information of the incident light into a spatially dependent signal that is analyzed by the camera. A fluidic platform is integrated onto the spectrometer for analyzing the fluorescence from moving objects. The target is continuously excited within an antiresonant waveguide, and its fluorescence spectrum is recorded as the object traverses the detection area.
