To measure the distance of an object, we propose a distance sensor that combines a tunable aperture operated by the thermal expansion of silicon chevron beams with a commercial camera similar to the automotive black box. The distance sensor is composed of a tunable aperture, a lens with an 8 mm focal length, and a 1/4-inch full high definition image sensor, where a tunable aperture is attached to the camera lens. To estimate the distance to the object, the blur difference is expressed in the form of a depth map using the depth from defocus algorithm. The mean error of distance estimation was 0.29 m. The area of the tunable aperture in the distance sensor is 1.18 mm² at OFF state and 2.79 mm² when the voltage is applied. The distance sensor can display an image and a distance simultaneously and can be applied to autonomous vehicles, drones, and robots.

为了测量物体的距离，我们提出了一种距离传感器，它将由硅 V 形梁的热膨胀操作的可调光圈与类似于汽车黑匣子的商用相机相结合。距离传感器由一个可调光圈、一个焦距为 8 毫米的镜头和一个 1/4 英寸全高清图像传感器组成，其中一个可调光圈连接到相机镜头。为了估计到物体的距离，使用离焦深度算法以深度图的形式表示模糊差异。距离估计的平均误差为 0.29 m。距离传感器中可调孔径的面积在关闭状态下为 1.18 mm ²和 2.79 mm ²当施加电压时。距离传感器可以同时显示图像和距离，可应用于自动驾驶汽车、无人机和机器人。
