| 摘要 |
The invention relates to a device (1) for simulating the human iris in the form of a controllable aperture, which comprises a first transparent carrier substrate (5) having a first conducting layer (7), a second transparent carrier substrate (6) having a second conducting layer (8), at least one liquid crystal layer (20), which is arranged between the carrier substrates (5, 6), and one polarization filter (9.1, 9.2) each at the proximal and distal ends, wherein the device (1) has at least two regions (2, 3), a first region (2), which has at least one liquid crystal layer (20), and a second region (3), which contains an energy supply apparatus, sensors (15), and a controller (16), such that the liquid crystals in the liquid crystal layer (20) can be polarized in dependence on the incident light intensity. |
