Optical phantoms (objects that have well-characterized optical properties that mimic human tissues) are essential to many biomedical optics research programmes. They can be used to validate new fNIRS array designs, test laboratory environments, assess system performance, and much more. At Gowerlabs, we have been developing and testing optical phantoms for many years. Our research has led us to produce a range of optical phantoms to meet the needs of fNIRS and biomedical optics research applications.
Anatomical Head Phantoms
Gowerlabs provides anatomically accurate optical phantoms for the adult, the 6-month old infant, and the newborn. Each phantom is hand-made from high-quality epoxy resin using an MRI-derived head-model that incorporates the key cranial landmarks.
We can also provide phantoms in a range of standard geometries, including flat slabs and hemispheres.
With default optical properties of absorption coefficient μa = 0.02 mm-1 and reduced scattering coefficient μs’ = 1 mm-1 at 800 nm, our phantoms are designed to mimic the known optical characteristics of the human head. Each phantom is supplied with a specification document that includes a detailed optical characterisation of the phantom material and its variability. Note that many other combinations of optical properties are available on request
