Portable electronic apparatus, spectrometer combined therewith, and method for detecting quality of test object by using the same

A spectrometer, comprising:

• a laser unit emitting an invisible-light laser light wave onto a surface of a test object so as for the surface of the test object to generate Raman scattered light;
• and
• a portable electronic apparatus receiving the Raman scattered light generated from the surface of the test object, the portable electronic apparatus comprising:
• a grating diffracting the Raman scattered light generated from the surface of the test object;
• a camera lens connected to the grating and capturing the Raman scattered light diffracted by the grating;
• a photoreceptor connected to the camera lens and configured to form image information according to the Raman scattered light captured by the camera lens;
• and
• a processing unit connected to the photoreceptor and configured to obtain a spectrum of the test object according to the image information formed by the photoreceptor.

A method, comprising:

• providing an object code and a first spectrum of a test object by a first terminal;
• transmitting the test object from the first terminal to a second terminal to transmit the object code and the first spectrum of the test object to the second terminal or a database;
• capturing a second spectrum of the test object by the second terminal using a portable electronic apparatus, wherein the portable electronic apparatus emits an invisible-light laser light wave onto a surface of the test object to generate Raman scattered light, diffracts the Raman scattered light generated from the surface of the test object, and captures the diffracted Raman scattered light to form image information according to the diffracted Raman scattered light and obtain the second spectrum of the test object;
• and
• determining a difference value between the second spectrum captured by the portable electronic apparatus and the first spectrum transmitted to the second terminal or to the database according to the object code, and detecting quality of the test object according to the difference value.
