在过去的二十年里，3D相机已被证明是机器视觉的下一次革命之一。然而，这些设备仍然是新兴技术，具有特别窄的市售设备集合。在本文中，第一个短波长红外（SWIR）的飞行时间（ToF）的3-D相机系统的概念和执行工作在1550 nm的波长。通过在开放式架构中解耦系统的光学和电气组件，我们不仅超越了片上集成解决方案的许多限制，而且还可以根据应用要求轻松更改成像设备。我们实现了高达150 MHz的调制频率，这超过了目前公布的其他大型调制器的常规值约5倍。调制频率的这种增加允许TOF相机具有显著更高的深度分辨率，而开放式架构设计允许高度可重新配置的设备，该设备可以针对特定的工作条件进行修改。
In the past two decades 3-D cameras have proven to be one of the next revolutions in machine vision. However, these devices are still an emerging technology with a particularly narrow set of commercially available devices. In this paper, the concept and execution of the first short wavelength infrared (SWIR) time-of-flight (ToF) 3-D camera system operating at a wavelength of 1550 nm is presented. By decoupling the optical and electrical components of the system in an open architecture we not only surpass many of the limitations of an on-chip integrated solution, but also can easily change the imaging device based on the requirements of the application. We achieve modulation frequencies up to 150 MHz, which exceeds the conventional values currently published for other large format modulators by about five times. This increase in the modulation frequency allows for a TOF camera with significantly higher depth resolution, while the open architecture design allows for a highly reconfigurable device that can be modified for specific working conditions.
