Techniques are provided for determining distance to an object in a depth camera’s field of view. In addition, the system comprises a results circuit coupled to the analyzer circuit. A first modular connector receives IPv4 Ethernet data which is converted to a raw data signal. The thickness of the lateral end part changes linearly from opposite lateral ends of the lateral center part to the opposite lateral ends of the slit. The LFP system includes a photonic crystal fiber based probe light source, a pump light source adapted to produce light pulses with microjoule or higher energy, a delay generator, computer, and a detector. The output magnet is disposed on the second opposed side of the layer.
