摘要：
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.
