Abstract
An optical coherence tomography imaging device (1) for imaging a retina of a human subject comprises a base (10) having a planar contact surface (11), an optical unit (30) providing a sample beam to scan the retina of the human subject and a head support (80) to be contacted by a head portion of the human subject, the head support (80) defining an entrance position of the sample beam entering an eye of the human subject. An angle between the sample beam at the entrance position and the planar contact surface (11) of the base (10) is 50 to 90°. This arrangement ensures that the head rests in a stable and well defined position with respect to the OCT optics. The risk of negative effects on the imaging process due to head movements, in particular due to movements during the scan time of the OCT device is considerably reduced. Furthermore, the device may assume a compact form factor.
