Abstract
The present invention provides an on-chip integrated cell phone spectrometer and a cell phone. The spectrometer includes: a detection system, including a cell phone lens and a focal plane detector integrated with a Bayer filter; and a spectral filter array, integrated at an edge of the Bayer filter, the spectral filter array including a plurality of filtering channels with different spectral transmittances, each filtering channel corresponding to one or more detector pixels, where the cell phone lens is configured to acquire a reflected light from an object under test, the focal plane detector is configured to acquire an intensity signal of the reflected light, and after different intensity signals corresponding to different filtering channels are obtained, a data processing system performs spectral reconstruction to obtain spectral data of the object under test.
