摘要： There is provided an optical system comprising an optical element (10) responsive to an applied signal to vary an optical property of the optical element (10), the variation of the optical property with the applied signal exhibiting hysteresis in a first range of values of the signal, and no hysteresis in at least one second range of values of the signal. The optical system further comprises a memory storing data representative of a variation of the optical property with either increasing values of the signal or decreasing values of the signal, and a controller configured to control the optical property of the optical element (10) by generating a control signal based on the stored data and applying the generated control signal to the optical element. In a case where the memory stores data representative of the variation of the optical property with increasing values of the signal, the controller is configured to use the stored data to change the value of the optical property from an initial value corresponding to a first value of the signal, to a subsequent value corresponding to a second value of the signal that is smaller than the first value of the signal, by setting the value of the control signal to a third value that is within the second range of values, and subsequently increasing the value of the control signal from the third value to the second value. Alternatively, in a case where the memory stores data representative of the variation of the optical property with decreasing values of the signal, the controller is configured to use the stored data to change the value of the optical property from an initial value corresponding to a first value of the signal, to a subsequent value corresponding to a second value of the signal that is greater than the first value of the signal, by setting the value of the control signal to a third value that is within the second range of values, and subsequently decreasing the value of the control signal from the third value to the second value.

摘要： The present invention provides an ophthalmic device comprising a light source (82; 84) arranged to emit a fixation target light, and a reflecting face (68A) arranged to reflect scanning light emitted by an emission section and to scan the scanning light in a specific direction by changing orientation, the emission section being a source of the scanning light that is different to the light source. The ophthalmic device further comprises a concave mirror face (70A) disposed such that the scanning light reflected by the reflecting face (68A) is incident on the ocular fundus of a subject's eye (38) when the subject's eye is placed at a focal point of the concave mirror (70) during use of the ophthalmic device, and is arranged such that, when the subject's eye (38) is placed at the focal point of the concave mirror (70) during use of the ophthalmic device and when the light source (82; 84) emits the fixation target light, the fixation target light and the scanning light are simultaneously incident on the ocular fundus via different optical paths both propagating via the concave mirror face (70A) and the focal point, the target fixation light following a predetermined optical path for fixing the gaze of the subject's eye (38).

摘要： Tomographic images are acquired of a posterior eye portion and an anterior eye portion of an examined eye using a single device. An ophthalmic device includes a scanning member, an objective lens, and an optical element. The scanning member scans light that has been emitted from a light source. The objective lens includes a first lens group and a second lens group in order from the scanning member side, and is an objective lens in which the second lens group is a lens group having a positive power. The optical element is capable of being inserted into and removed from an optical path between the second lens group of the objective lens and the scanning member. In a case in which the optical element is not inserted into the optical path, the objective lens configures a first observation optical system, and light that is scanned by the scanning member is focused in a first region of an examined eye. In a case in which the optical element has been inserted into the optical path, the objective lens and the optical element configure a second observation optical system, and light that is scanned by the scanning member is focused in a second region that is different from the first region of the examined eye.
