论文摘要
基于单像素检测器（SPD）的无图像跟踪方法可以以非常高的帧速率跟踪移动对象，但是它们很少能同时实现此类对象的同时成像。在这项研究中，我们提出了一种同时获取翻译对象的相对位移和图像的方法。四个二进制傅立叶图案和两个差分hadamard模式用于调制对象的一帧，然后通过SPD获得调制的光信号。移动对象的相对位移和图像可以与检测一起逐渐获得。提出的方法不需要对对象及其运动的任何先验知识。该方法已通过模拟和实验验证，以3332 Hz的形式达到了3332 Hz的帧速率，以使用20000-Hz数字微型效果设备的空间分辨率为$ 128 \ times 128 $像素以$ 128 \ times 128 $像素的空间分辨率获得相对位移。这种提出的方法可以扩大无图像跟踪方法的应用，并获取有关移动对象的空间信息。
Image-free tracking methods based on single-pixel detectors (SPDs) can track a moving object at a very high frame rate, but they rarely can achieve simultaneous imaging of such an object. In this study, we propose a method for simultaneously obtaining the relative displacements and images of a translational object. Four binary Fourier patterns and two differential Hadamard patterns are used to modulate one frame of the object and then modulated light signals are obtained by SPD. The relative displacements and image of the moving object can be gradually obtained along with the detection. The proposed method does not require any prior knowledge of the object and its motion. The method has been verified by simulations and experiments, achieving a frame rate of 3332 Hz to acquire relative displacements of a translational object at a spatial resolution of $128 \times 128$ pixels using a 20000-Hz digital micro-mirror device. This proposed method can broaden the application of image-free tracking methods and obtain spatial information about moving objects.
