Snapshot imaging spectrometer for mobile phone
At present, the mobile camera has the ability to obtain imaging information in the space (x-y direction) and depth (z direction) dimensions while the acquisition of spectral information has been stuck in RGB tricolor. Limited by the size of the mobile platform, the traditional imaging spectrometer is difficult to be embedded. Based on the integrated manufacturing technology of multi-channel array filters, micro-lens array imaging and integration, this paper completes the overall design of the system, the design and manufacture of the key components and overall assembly. The spectral imaging is verified experimentally. The overall physical size of the system is less than Φ6 × 6 mm, the spectral resolution is 8nm, and the spectral range is 0.53-0.68μm. The experimental results show that the spectral curves of any part of the object can be obtained by imaging the object with different colors, which verifies the design index of the snapshot spectrometer. With the basic conditions of embedding the technology into mobile phones, the system is expected to promote the integrated applications of imaging spectrometers.
