本文介绍了一个全数字闭环（ADCL）干涉式光纤陀螺（IFOG）的设计细节和特性的正弦波偏置调制和SLED发射在1288.9 nm，在TUBITAK UME构建的原型。ADCL-IFOG的电子反馈部分由16位AD 7714 YN ADC和14位LTC 1667 CG DAC组成，由89 C51单片机控制和同步。ADCL-IFOG原型的平均灵敏度（以施加到相位调制器的误差电压为单位）计算为132.65 μ V/（A度/h），等于比例因子7.53888（A度/小时）/mV，标准偏差为0.85%，范围为1-15270（A度/h）旋转速率，对应于从0.00115到17.57448（A度）变化的Sagnac相移范围。在23.0A ℃时，样机的最大峰间噪声和偏置稳定性分别为4.97和1.48（A度/h）。在23.0-42.0A ℃的温度范围内观察到噪声和偏置稳定性的变化。
This paper describes the design details and the characterization of an all digital closed-loop (ADCL) interferometric fiber optic gyroscope (IFOG) Prototype with sine wave biasing modulation and SLED emiting at 1288.9 nm, constructed in TUBITAK UME. Electronic feedback section of ADCL-IFOG is composed of 16 bit AD7714YN ADC, 14 bit-LTC1667CG DAC, fully controlled and synchronized by 89C51 microcontroller. The averaged sensitivity of the ADCL-IFOG prototype in unit of error voltage applied to the phase modulator was calculated as 132.65 mu V/(A degrees/h) which equals to a scale factor of 7.53888 (A degrees/h)/mV with a standard deviation of 0.85% for a range of 1-15270 (A degrees/h) rotation rate, corresponding to a range of Sagnac phase shifts varying from 0.00115 to 17.57448 (A degrees). The maximum peak to peak noise and the bias stability of the prototype were determined as 4.97 and 1.48 (A degrees/h) at 23.0A degrees C, respectively. The variation of the noise and bias stability on a temperature range of 23.0-42.0A degrees C was observed.
