Optical system for imaging an object and method for operating said optical system

摘要

An optical system for imaging an object includes a objective, an image stabilizing unit, an image plane and a drive unit, which is arranged at the image stabilizing unit and provided for moving the image stabilizing unit. The optical system includes a control unit. A signal from the control unit is forwarded to a first high-pass filter. The control unit has an output line and the high-pass filter has a filter output line. Both the output line and the filter output line are arranged at an addition unit such that an actuation signal from the control unit and an output signal from the high-pass filter are added to produce an addition signal. The addition unit is arranged at the drive unit in such a way that the addition signal is used for actuating the drive unit and for moving the image stabilizing unit.

主权项

1. An optical system for imaging an object, comprising:
at least one first objective; at least one first image stabilizing unit; at least one first image plane, wherein, as seen from the first objective in a direction of the first image plane, the first objective is arranged first along a first optical axis, followed by the first image stabilizing unit and the first image plane; at least one first drive unit, which is coupled to the first image stabilizing unit and provided for moving the first image stabilizing unit; and at least one first control unit for actuating the first drive unit, wherein a first high-pass filter is connected between the first control unit and the first drive unit such that a signal from the first control unit is forwarded to the first high-pass filter, the first control unit has a first output line, at least one first low-pass filter, and at least one first integration unit which is connected downstream of the first low-pass filter, the first high-pass filter has a first filter output line, both the first output line and the first filter output line are coupled to a first addition unit such that an actuation signal from the first control unit and an output signal from the first high-pass filter are added to produce a first addition signal, and wherein the first addition unit is coupled to the first drive unit in such a way that the first addition signal is used for actuating the first drive unit and for moving the first image stabilizing unit.
