The implementation of a thermal endoscope based on the LWIR camera cores Lepton and a custom miniaturized electronics is reported. The sensor and the PCB can be inserted into a cylindrical protective case of diameter down to 15mm, inox tube or plastic, 3D printable envelope, with an optical window in Germanium. Two PCBs were developed for assembling the endoscope in two different schemes, to enable frontal or lateral thermal vision setup. The thermal endoscope unit is controlled by a Raspberry external unit. The Infrared Vision Software is provided for controlling the acquisition of thermal frames, and for the thermographic calculation of the object temperature from the input parameters on object surface emissivity and environment. In general, the device enables to perform thermography in applications in which traditional larger equipment cannot be employed, as nondestructive diagnostics in confined space in the engineering field. The thermal endoscope was designed with dimensions also compatible for robotic-assisted/traditional minimally-invasive surgery.
本文报道了一种基于LWIR相机核心Lepton和定制小型化电子设备的热内窥镜的实现。传感器和印刷电路板（PCB）可以插入直径低至15毫米的圆柱形保护壳中，该保护壳可以是不锈钢管或塑料管、3D可打印外壳，带有锗光学窗口。开发了两块印刷电路板，用于以两种不同方案组装内窥镜，以实现正面或侧面热视觉设置。热内窥镜单元由树莓派外部单元控制。提供了红外视觉软件，用于控制热帧的采集，并根据物体表面发射率和环境的输入参数对物体温度进行热成像计算。总体而言，该设备能够在传统大型设备无法使用的应用中进行热成像，例如工程领域受限空间内的无损诊断。热内窥镜的设计尺寸也适用于机器人辅助/传统微创手术。
