计算机控制的窄脉冲光谱/时间分辨测量系统

A Narrow Pulse Spectrum/Time Resolution Measurement System Controlled by a Microcomputer

本文介绍一种由Boxcar积分器与光栅单色仪配合、计算机控制的光谱、时间分辨测量系统。结果表明该系统能够测量波长-时间-强度(W-t-I)三维关系和进行某一剖面如波长-强度(W-I)、时间一强度(t-I)的二维测量,而且能够将淹没在噪声中的窄脉冲波形恢复出来。在计算机数据站管理下,可实现测量数据实时或事后处理和绘图。

This paper discribed a spectrum/time resolution measurement system combined with a Boxcar integrator and a grating monoch- rowator controlled by a microcomputer. The result shows that this system not only can measure 3-D wave-time-intensity(W-T-I) and 2-D, such as wave-intensity (W-I), time-intensity (T-I), but also can restore a week narrow pulse which was submerged by noise. Under the management of data station the measured data can be processed and drawn either on-line or off-line.
