为获取远程、高速目标的距离信息,研制了一种基于合作目标的高重频人眼安全激光测距仪,该测距仪采用重频达80 Hz的1 550 nm激光器作为激光光源。经外场试验验证,在能见度10 km的情况下,对合作目标(角反射器),人眼安全激光测距仪的作用距离为20 km,同时,测距仪重频达30 Hz,测距精度2 m(RMS)。该测距仪满足了系统的技术要求。

To acquire the distance of high speed remote target, an eye-safe laser rangefinder with high repetition frequency based on laser cooperative targets is introduced in this paper. The repetition frequeacy of the laser is 80 Hz, and the wavelength is 1 550 nm. It is tested that the operating range of the laser rangefinder is 20 km (to laser retroreflector) under the circumstance of 10 km visibility. The repetition frequency of the rangefinder is 30 Hz, and its ranging accuracy is 2 m(RMS). The rangefnider meets the technical requirements of system.
