ＦＭ—１０００超小型水下摄像机是一种便携式水下监视摄录仪器。本文扼要阐述了该仪器的基本原理、技术性能、指标以及各种功能的使用。着重探讨了此仪器自１９９２年至１９９５年在长海县海水增养殖生产中的应用试验及技术改进和配套等情况。试验结果表明：ＦＭ—１０００超小型水下摄像机，在透明度不低于５ｍ，水深不超过４０ｍ的海域内，能够清晰的监视摄录到海底底质、敌害，底播增殖品种及其它贝、藻、鱼类等在海底栖息生存的图像资料
The FM-1000 Subminiature Underwater Camera is a portable underwater surveillance camera. This article briefly describes the basic principles of the instrument, technical performance, indicators and the use of various functions. This paper mainly discusses the application experiment, technical improvement and matching of this instrument in the breeding of seawater in Changhai County from 1992 to 1995. The test results show that the FM-1000 ultra-small underwater camera can clearly monitor and record the seabed sediment, predator, bottom-propagating species and other seashells in the sea area with the transparency of not less than 5m and the water depth of not more than 40m.
