A line-scanning ophthalmoscope includes a light source to provide a light beam to an object of interest, a beam separating device to receive the light beam, provide the light beam to a scanning device and substantially separate the light beam and the returning light beam from the object of interest, a scanning device to direct the light beam to the object of interest for scanning the object of interest； to receive the light beam returning from the object of interest； and to direct at least part of the reflected light beam towards a detector； and a further scanning device to convert the light beam to a line-shaped light beam.
