Aspects of the disclosure relate to systems and techniques for inspecting seals for high altitude balloons. In one example, a system may include a reflective surface, a translucent material on the reflective surface, and a movable light source configured to move along the reflective surface and provide light to the reflective surface. The light is provided such that it is reflected from the reflective surface and through the translucent material in order to backlight a balloon envelope seal for inspection. A method for inspecting a balloon envelope seal may include placing balloon envelope material on a table, forming a seal between portions of the material, moving a light over the seal, shining light onto a reflective portion of the table below the seal to backlight the seal, and inspecting the seal using the backlighting of the seal.

A substrate surface information detection device and a substrate surface information detection method are disclosed. The device includes a spray source and an image sensor, wherein the spray source is configured to uniformly spray droplets onto a surface of a substrate-under-test or form a liquid flow on the surface of the substrate-under-test, and the image sensor is configured to record image information of the droplets or the liquid flow. According to the substrate surface information detection device and substrate surface information detection method, defects on the surface of the substrate before the PI coating can be prevented and avoided, the production time can be shortened, and the production efficiency can be promoted and the product yield can be improved.
