The invention relates to a portable miniature spectrograph. The portable miniature spectrograph comprises a two-dimensional spectrum sensor, a sensor board, an interface board, a core board, a connecting flexible board and a housing, wherein the two-dimensional spectrum sensor is used for receiving an optical signal of a to-be-detected object and acquiring two-dimensional image information and two-dimensional spectrum information of the to-be-detected object from the optical signal. The two-dimensional spectrum sensor is mounted on the sensor board. The sensor board is in communication connection with the interface board through the connecting flexible board so that the sensor board is overturned relative to the interface board. The interface board is in communication connection with the core board through a socket. Furthermore the interface board and the core board are overlapped and fixed. The core board is used for transmitting a control instruction and processing the two-dimensional image information and the two-dimensional spectrum information. The portable miniature spectrograph can perform large-area detection on the object. Furthermore the spectrograph realizes small size and high convenience in carrying. A person can perform routine spectrum detection on objects such as daily objects and food in daily life for obtaining a detecting result, thereby facilitating people's life.
Description
technical field [0001] The invention relates to the field of spectrum detection, in particular to a portable miniature spectrometer. Background technique [0002] In the field of spectral detection, traditional spectrometers are bulky and inconvenient to carry. They can only be used in fixed places, and are mostly used for industrial production and experimental data detection. They cannot meet the detection of daily necessities and food in people's daily life. For example, in today's life, food safety problems are becoming more and more serious. Food problems such as excessive pesticide residues, dyeing agents, and preservatives are very common. It is difficult for people to distinguish with the naked eye and experience in the daily purchase process. However, due to the particularity of spectral detection, there is a lack of portable spectrometers that can be used for detection of daily necessities. [0003] Traditional spectrometers can only detect samples in a small range...
