A new, non-contact, three-dimensional (3D) bullet signature measuring system based on a chromatic confocal sensor is developed. The system is composed of a precision rotary table and a chromatic confocal sensor. The measurement uncertainty of the system is less than 1 µm. When measuring the surface topography of the object, the sensor acquires wavelength information reflected from the object instead of intensity information. This advantage is very suitable to bullet signature measurements. The chromatic confocal sensor works in the point measuring mode and can acquire data continuously with high speed. One round section measurement on the bullet body takes less than 1 minute.
开发了一种基于彩色共焦传感器的新型非接触式三维（3D）子弹特征测量系统。该系统由精密旋转台和彩色共焦传感器组成。系统的测量不确定度小于1微米。在测量物体表面形貌时，传感器获取从物体反射的波长信息而非强度信息。这一优势非常适合子弹特征测量。彩色共焦传感器工作在点测量模式下，能够高速连续采集数据。对子弹体进行一次圆形截面测量所需时间不到1分钟。
