要是回到七十年代初去制造这种仪器,那电路一定会很复杂。但是今天的电路,由于应用中大规模集成器件,面目已大大改观了。从外观上说,测色色差计的整个电路(不包括微机部分),其复杂程度末必能抵得上十几年前复杂物理光学测量仪器的一个小单元。试看下面的简要说明。一、WSC电路的组成 WSC电路只有三部分:电源、光电探测,模数转换及数据处理。光电探测部分包括4个光电池及4个I—V变换电路。模数转换及数据处理部分包括一个多输入端A/D变换板及一台通用微型机。电源分
Back to the beginning of the seventies to create this instrument, that circuit will be very complicated. But today’s circuit, due to the application of large-scale integrated devices, the face has greatly changed. In appearance, the entire circuit (excluding the computer part) of the colorimetric chromatic aberration meter will not be able to withstand the complexity of a small unit of complex physical optical measuring instruments more than ten years ago. Try the brief instructions below. First, the composition of the WSC circuit WSC circuit only three parts: power supply, photoelectric detection, analog-digital conversion and data processing. Photoelectric detection part includes four photovoltaic cells and four I-V conversion circuit. Analog-digital conversion and data processing part includes a multi-input A / D converter board and a universal microcomputer. Power points
