Abstract

The medical optical sensor (10) comprises at least one light emitter (20) for emitting light (21) directed to a part of the skin (50) of a patient and at least one photo- detector (30) for detecting light (31) reflected from the skin (50). A housing (40) for carrying the at least one light emitter (20) and the at least one photo-detector (30) is provided, where the housing (40) has a contact area with the skin (50). The at least one light emitter (20) is positioned within the housing (40) such that emitted light (21) impinges on the skin (50) in a central part of the contact area. The at least one photo-detector (30) is positioned in a peripheral part of the housing (40) such that light reflected (31) from the skin (50) to the outer part of the contact area is detectable by the at least one photo-detector (30).
