Embodiment 1
[0036] Embodiment 1: as figure 1The device for measuring the three-dimensional distribution of radiation light field includes a drilled hemispherical shell 1, an optical fiber 2, a drilled disk 3, an adjustable diaphragm 6 and an imaging system. All components are coaxially distributed along the main axis of the device, the adjustable diaphragm 6 is located at the bottom of the device, the drilled hemispherical shell 1 is located on the adjustable diaphragm 6, the lower surface of the adjustable diaphragm 6 coincides with the equatorial plane of the drilled hemispherical shell 1, And the center of the lower surface of the adjustable diaphragm 6 coincides with the center of the sphere of the drilled hemispherical shell 1 . The drilling disc 3 is located on the drilling hemispherical shell 1, and the two are connected by a number of optical fibers. The number of optical fibers is equal to the number of holes on the drilling hemispherical shell and the number of holes on the disc...
Embodiment 2
[0038] Embodiment 2: as figure 2 The device for measuring the three-dimensional distribution of the scattered light field on the surface of an object includes a drilled hemispherical shell 1, an optical fiber 2, a drilled disk 3, a light source power monitor 8, a beam splitter mirror 9, an adjustable diaphragm 6, a light source system and an imaging system . The structure of the device is based on the same structure as that of the device described in Embodiment 1, with the addition of a light source power monitor 8, a beam splitter 9 and a light source system. The beam splitter 9 is fixed between the disk 3 and the lens 5, and its normal line forms an angle of 45 degrees with the main axis of the device. Light source system 7 is made up of light source 18, lens 15, 17 and pinhole 16, and light source system 7 is positioned between disc 3 and lens 5, on the side of beam splitter 9, and its optical axis is perpendicular to the main axis of device, and light source system 7 As...
