Document Type and Number:
Japanese Patent JP2012525184
Kind Code:
A
Abstract:
The invention provides a scanning ophthalmoscope for scanning the retina of an eye and method of operating the same. The scanning ophthalmoscope comprises a source of collimated light, a first scanning element and a second scanning element. The source of collimated light and the first and second scanning elements combine to provide a two-dimensional collimated light scan from an apparent point source. The scanning ophthalmoscope further comprises a scan transfer device, wherein the scan transfer device is a reflective element and has two foci and the apparent point source is provided at a first focus of the scan transfer device and an eye is accommodated at a second focus of the scan transfer device, and wherein the scan transfer device transfers the two-dimensional collimated light scan from the apparent point source into the eye. The first and second scanning elements have operating parameters which are selected to control the direction of the two-dimensional collimated light scan from the apparent point source and/or adjust the dimensions of the two-dimensional collimated light scan from the apparent point source.
