    • Techniques for measuring ink motion are provided. In one embodiment, an apparatus includes a pulse generator, a waveform generator, a lighting unit, an image capturing unit, and a controller. The pulse generator is configured to generate a first trigger signal pulse and a second trigger signal pulse based on the control signal, a second control signal pulse being generated after a variable delay to the first trigger signal pulse. The waveform generator is configured to generate a waveform to drive a printing device based on the first trigger signal pulse. The lighting unit is configured to illuminate ink in the printing device based on the second trigger signal pulse. The image capturing unit is configured to capture a plurality of images of the ink, each image captured at a different time point with a different delay between the first and second trigger signal pulses.
    • 提供了测量墨水运动的技术。 在一个实施例中,一种装置包括脉冲发生器,波形发生器,照明单元,图像捕获单元和控制器。 脉冲发生器被配置为基于控制信号产生第一触发信号脉冲和第二触发信号脉冲,第二控制信号脉冲在对第一触发信号脉冲的可变延迟之后产生。 波形发生器被配置为基于第一触发信号脉冲产生用于驱动打印装置的波形。 照明单元被配置为基于第二触发信号脉冲照亮打印装置中的墨水。 图像捕获单元被配置为捕获墨水的多个图像,每个图像在第一和第二触发信号脉冲之间以不同的延迟在不同的时间点捕获。
