Abstract

The invention provides a portable integrative measuring device of a photoelectric spectrum analyzer. The measuring device comprises an optical unit and an electronic unit. A photoelectric detector (12) is used as a detected object, an embedded processor ARM9 (18) controls a singlechip controller (17) to further control the opening of a digital switch (14), a signal amplifying unit (15) amplifies optical signals acquired by the photoelectric detector (12) and transmits the amplified optical signals to an A / D converter (16), the singlechip controller (17) controls the A / D converter (16) to finish digital-to-analogue conversion and transmits data to the embedded processor ARM9 (18) through a serial port, and an execution program fits and processes the data to acquire a spectral characteristic curve and a photoelectric characteristic curve of the detected photoelectric detector (12) and displays the results on a liquid crystal touch screen (19). The measuring device can be applied to teaching and product detection, has small volume, needs no computer, and is convenient to use.

Description

technical field [0001] The invention relates to an embedded photoelectric spectrum analyzer. Background technique [0002] With the continuous development of optoelectronic technology and the continuous development and improvement of optoelectronic device products, the application of optoelectronic products has penetrated into people's daily life. Photodetector devices such as photodiodes, phototransistors, photoresistors, and photocells Used in military, civil, industrial, scientific research and medical fields. The photoelectric spectral characteristics are an important characteristic index for evaluating the performance of photodetector devices. Only by understanding the properties of corresponding photodetector devices can they be better applied and developed in various fields. At the same time, with the popularization of these basic photodetector devices, in the teaching of understanding and learning photoelectric theory, people pay more attention to the real meaning o...
