Systems, devices and methods according to these exemplary embodiments provide for memory management techniques and systems for storing data. The light-transmitting member includes a light-transmitting base disposed to be in contact with either the sensor substrate or the light-blocking substrate, and a light-transmitting resin which is filled between the base and the sensor substrate or the light-blocking substrate. The method additionally includes reducing the first proximal tip diameter to a smaller implantable proximal tip diameter. As a result, it is not necessary to interpolate pixels, and the deterioration of picture quality arising from interpolation of pixels is prevented. After filtering, Stokes parameter based images can be obtained by demodulating and inverse Fourier transforming the filtered frequency domain data. Cooled synthetic gas is used to power a gas turbine as a fuel to produce electricity.
