An innovative approach to a non-destructive lock mechanism examination by means of X-ray computed tomography (CT) was involved in a careful opening of a locked 19th century chest missing the key, as an interdisciplinary cooperation with the restorers. In regard of the exploration and conservation of such locked objects, their opening is important to the restorers. However, the opening may be complicated, if not impossible, without damaging the object when the key is missing. Moreover, the historical locks might be equipped with protective mechanisms. Despite the exceeding dimensions and the weight of the steel chest, a CT analysis was performed, which enabled a detailed exploration of the lock based on a system of levers and bolts handled by a single key, located in a case on the inside of the chest lid, including the dimensions essential for manufacturing of a new key copy. Moreover, two secret protective mechanisms were revealed, as well as all the damages of the object.
一种创新的非破坏性锁机制检查方法是通过 X 射线计算机断层扫描（CT）实现的，该方法用于仔细打开一把 19 世纪的锁着的箱子，这把箱子没有钥匙，这是与修复师的跨学科合作。对于这种锁着的物品的探索和保护，打开箱子对修复师来说很重要。但是，如果钥匙丢失，而不损坏物品，打开箱子可能会很复杂，甚至不可能。此外，历史悠久的锁可能配备有保护机制。尽管钢箱的尺寸和重量超过了预期，但还是进行了 CT 分析，这使得可以根据一套由单个钥匙控制的杠杆和螺栓系统，对锁进行详细的探索，其中包括制造新钥匙副本所需的尺寸。此外，还揭示了两个秘密的保护机制，以及物体的所有损坏。
