DROP IMAGE SENSING |
| 摘要 |
A sensor images drops ejected from a printhead nozzle. The sensor has two parallel spaced-apart rows of imaging pixels. In one example, a lens projects an image of a drop ejected from a printhead onto the rows sequentially as the drop travels along a trajectory. |

1. An imaging sensor assembly, comprising:
a two-dimensional imaging sensor having two parallel, spaced-apart rows of imaging pixels, each pixel producing a multilevel signal indicative of an illumination intensity impinging that pixel; and a lens projecting an image of a drop ejected from a printhead onto the rows sequentially as the drop travels along a trajectory. |
