Simultaneously achieving circular symmetry and diminishing effects of optical defects and deviations during real time use of optical devices

摘要

A method for simultaneously achieving circular and diminishing effects of optical defects and deviations during real time use of optical devices, and, a corresponding device and system for implementing the method thereof. The method features rotating an entire optical device (78), rotating at least one optical part (90) of an entire optical device such as an optical assembly or an optical element (92) during real time viewing or projecting by the optical device, in order to spread and blur the optical defects and deviations present in the at least one optical part of the optical device. In a first embodiment of the method, an optical rotation device is activated and controlled for rotating at least one optical part of an optical device during real time use of a viewing or projecting optical device. In a second embodiment of the method, there is included a step for aligning the optical axis of the at least one optical part of the optical device with respect to the rotation axis. In a first, simple, yet practical, embodiment of an optical rotation device for rotating the at least one optical part of the optical device, there are provided means and mechanisms for manual alignment during real time use of an optical device, whereas, in a second, more advanced, embodiment of an optical rotation device for effecting the rotation of the optical part of the optical device, there are provided means and mechanisms for highly accurate and automatic aligning of the optical axis of the optical axis of the optical device with the rotation axis, thereby simultaneously achieving a high level of circular symmetry with respect to the optical part of the optical device, and significant diminishment of optical defects and deviations in at least one optical part of the optical device.
