Abstract:
A hologram image acquiring apparatus may include: a linear polarizer that filters incident light reflected by an object into a polarized component of a specific angle; a spherical lens that partially converts light that is incident through the linear polarizer to a spherical waveform; and a phase shifter that converts a part of the light incident through the spherical lens to a plane waveform having a different phase per pixel unit.
Abstract:
A control device is provided which controls wireless communication linkage between communication devices. The control device includes a communication unit configured to perform wireless communication with first and second communication devices; a user interface unit configured to generate a communication unit active signal according to a control of a user; and a control unit configured to activate the communication unit in response to the communication unit active signal. The communication unit receives communication linkage information for communication linkage between the first and second communication devices from the first communication device and sends the communication linkage information to the second communication device.
