摘要

腔型电校绝对辐射计是通过测量腔与热沉之间的温升这个二次参数

并做为基准实施精密的电校准补偿。从而实现对入射光辐射的绝对定标。本文设计的腔型绝对辐射计的电校准测量系统由微弱信号检测、可编程电源等部分组成

是一个以微计算机为工作核心的多外部设备分时控制系统。测量辐射的量程为1个太阳常数

分辨率为0.05mW/cm

Abstract

The electric-calibrated absolute cavity radiometer realises absolute calibration of incident radiation

by measurement different temperature between cavity and heat sink

and as a standard of implementing precise electric compensation.The electric-calibrated measurement system of absolute cavity radiometer discussed in this paper consists of detection of weak single

programmable precise power supply

and so on.It is a multiple external equipmerit and distributing-time control system on the centre of the computer measuring radiation range is one solar constant

resolution is 0.05mW/cm
