Title:
マイクロミラーバランシングされた眼科顕微鏡
Document Type and Number:
Japanese Patent JP7449389
Kind Code:
B2
Abstract:
The ophthalmologic microscope has an illumination device for projecting light onto an eye to be observed and a microscope device with a camera to view the eye. The illumination device generates pulsed light. The light is pulsed at least at twice the frame rate of the camera to reduce flicker. The illumination device uses an array of micro-mirrors as spatial light modulator, and the mirrors are controlled for a balanced deflection over the frame cycles, which allows to increase the service life of the microscope.
