摘　　要：提出了一种便携式色温表的研制方案，在公式法测量原理的基础上，采用光一频转换的硒色敏传感器，利用单片机和数字电路结合软件修正进行系统控制和计算色温值。按照色温表检定规程要求进行了检测，结果表明色温表的各项技术指标均达到规程JJG212—2003的要求。A new scheme for the portable color temperature meter is proposed, which is based on the color temperature experience formula, using the selenium color sensors based on light-frequency conversion, the singleehip, digital circuit and software correction to control the system and calculate the color temperature. According to JJG212--2003, tests are performed. The resuhs show that the technique specifications of the color temperature meter all meet or excel the requirements of JJG212--2003.
