On-chip integrated mobile phone spectrometer and mobile phone

Abstract

The invention discloses an on-chip integrated mobile phone spectrometer and a mobile phone, and the on-chip integrated mobile phone spectrometer comprises a detection system which comprises a mobile phone lens and a focal plane detector integrated with a Bayer filter; a spectrum optical filter array is integrated on the edge of the Bayer filter, the spectrum optical filter array comprises a plurality of optical filter channels with different spectrum transmittances, and each optical filter channel corresponds to one or more detector pixels; and the mobile phone lens is used for collecting reflected light rays of a detected object, the focal plane detector is used for collecting intensity signals of the reflected light rays, and after different intensity signals corresponding to different filtering channels are obtained, the data processing system carries out spectrum reconstruction to obtain spectrum data of the detected object. The spectrum optical filter array is integrated on the focal plane detector to form the spectrometer, complex and huge light splitting elements and systems are not needed, the structure is compact, the spectrum optical filter array only needs to be integrated on the edge of the Bayer filter, additional accessories are not needed, and the spectrometer has the advantages of being high in integration level, high in response speed, good in spectrum resolution and the like.

Description

technical field [0001] The invention relates to the technical field of spectrometers, in particular to an on-chip mobile phone spectrometer and a mobile phone. Background technique [0002] The spectrometer can measure the spectral information by obtaining the reflected light or emitted light on the surface of the object, so as to know the weight and composition of the substance contained in the measured object. It is often used in environmental pollution, food hygiene, authenticity identification, light source detection, mineral exploration and other fields . Traditional spectrometers are bulky and expensive, and are often used in specific scenarios such as laboratories and production workshops. They are very inconvenient to carry, which severely limits the popularization and application of spectrometers in daily life. With the continuous improvement of living standards, people pay more and more attention to issues such as food safety, the quality of medicines, and the fre...

Problems solved by technology

The method of external equipment still requires the user to carry additional spectrometer equipment. Although the miniature spectrometer equipment is small in size and light in weight, this method is not portable enough, and it is still difficult to perform detection anytime and anywhere

The method of adding additional accessories inside the mobile phone has greatly improved the portability, but it will increase the power consumption and cost of the mobile phone, and affect the appearance
