1981年似乎就明白,虽然光纤陀螺有很大潜力,但在分立光学元件制作的试验系统变成实用仪器前,仍有许多问题有待解决。这个观点已为伦敦学院B·Culshaw等人所证实。他们认为对速率应用来说,尽管集成光学元件是重要的,但测速陀螺显然是最有前途的领域。尺寸较小以及依靠大量生产而使成本较低也都需要。在1976年开始的一个计划中,英国航空动力学小组正在进行宇航电子学应用 It seems to be understood in 1981 that although fiber optic gyros have great potential, there are still many problems to be solved before the experimental system for making discrete optical components becomes a practical one. This view has been confirmed by London College B. Culshaw et al. They believe that for speed applications, although integrated optics are important, it is clear that speed gyros is the most promising area. Smaller sizes and lower costs are also needed for mass production. In a plan that began in 1976, the British Aeronautical Dynamics Group is conducting aerospace electronics applications
