Abstract
Various improvements to three dimensional imaging systems having inflatable membranes are disclosed. These improvements include, among other things, a proximity sensor that can be used to warn a user of the device when approaching a feature in a cavity, such as an eardrum in an ear canal; or optical sensors with an optical coating matching the refractive index of the medium in which the optical sensors are deployed, to improve data acquisition.
