Monitoring of infants in an incubator may use cameras to measure vital signs and other medical parameters, including oxygen saturation of arterial blood. However, the images obtained by these cameras suffer from a reduced signal-to-noise ratio due to specular reflectance from light reflecting off the skin of the infant. By including radiation scattering structures within the incubator walls and light sources arranged along the edges of the incubator walls, diffuse illumination may be achieved, specular reflectance may be reduced, and the above-mentioned adverse affects on the signal-to-noise ratio of the camera images may be avoided and/or reduced.
