摘要： Camera device and method for shooting light having at least two wavelength bands are disclosed. The camera device includes a first camera containing a first lens for receiving light having a first wavelength band; a second camera including a second lens for receiving light having a second wavelength band which is different from the first wavelength band, the second lens being disposed facing the first lens of the first camera; and a parabolic mirror set between the first camera and the second camera, able to let the light having the first wavelength band penetrate therethrough, and at the same time, reflect the light having the second wavelength band. The first camera is a non-fisheye camera. The first lens is a non-fisheye lens. The second camera and the parabolic mirror form a catadioptric camera. The aperture stop of the non-fisheye lens coincides with the focal point of the parabolic mirror.

摘要： An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.
