为了实现紧凑的运动传感电路，我们提出了一种产生一维光流的简单模拟MOS电路。在该电路中，光流由多个基于生物运动检测器的局部运动传感器来计算。与传统的速度传感电路相比，模仿生物运动检测器的结构使电路结构变得非常简单。利用集成电路重点仿真程序(SPICE)进行的大量仿真结果表明，所提出的电路能够计算运动光斑的局部速度，并显示运动光斑的方向选择性，这意味着采用标准的模拟超大规模集成电路(VLSI)工艺可以实现高分辨率的运动传感芯片。
We propose simple analog MOS circuits producing one-dimensional optical flows aiming at the realization of compact motion-sensing circuits. In the proposed circuit, the optical flow is computed by a number of local motion sensors which are based on biological motion detectors. Mimicking the structure of biological motion detectors made the circuit structure quite simple, compared with conventional velocity sensing circuits. Extensive simulation results by a simulation program of integrated circuit emphasis (SPICE) indicated that the proposed circuits could compute local velocities of a moving light spot and showed direction selectivity for the moving spot, which implies that a high-resolution motion-sensing chip can be realized using standard analog very large-scale integration (VLSI) technology.
