Embodiment
As shown in Figure 1, a kind of many field detection camera lens, comprises the full filed zoom camera lens 1, spatial filter 2, discrete visual field lens group 3, the radial contracting bundle device 4 that arrange in turn along light path.Spatial filter 2 can filtering ineffective sample or visual field, only allows target sample or field of regard to pass through, forms several field of regards.As shown in Figure 2, several imaging lens 8 that discrete visual field lens group 3 comprises camera lens fixture 7 and is distributed on camera lens fixture 7, the distributing position of imaging lens 8 is consistent with the field of regard number that spatial filter 2 filters, and distributing position one_to_one corresponding.Radial contracting bundle device 4 comprises reflecting surface structure, and reflecting surface structure is biconial reflecting surface structure or conical reflecting surface structure.Be biconial reflecting surface structure in the present embodiment, the setting corresponding with imaging lens 8 of biconial reflecting surface structure.In the present embodiment, biconial reflecting surface structure is made up of one group of male conical reflecting surface 5 be parallel to each other and recessed conical reflecting surface 6, and field of regard after male conical reflecting surface 5 and recessed conical reflecting surface 6 liang of secondary reflections, is imaged onto on imageing sensor successively.
When sample or visual field focus on spatial filter 2 with filtering ineffective sample or visual field by full filed zoom camera lens 1, form several target sample or field of regard, target sample or field of regard are imaged onto on radial contracting bundle device 4 by discrete visual field lens group 3, as shown in Figure 3, target sample or field of regard change original light path position after the male conical reflecting surface 5 that is parallel to each other and recessed conical reflecting surface 6 liang of secondary reflections, and its Y-axis displacement is:
θ is the tapering of male conical reflecting surface 5, and d is the spacing between male conical reflecting surface 5 and recessed conical reflecting surface 6.Different θ values and d value are set according to actual measurement demand, obtain different displacement Y, ensure target sample or the equal imaging of field of regard on the image sensor, realize the synchro measure of Multi-example or many visual fields.
