    Abstract: Bias or background charge (sometimes known as ''''fat zero'''' charge) is introduced into a charge coupled device (CCD) image sensing array by applying radiation to the substrate through the surface opposite the one receiving the image. For example, in the case of a front surface illuminated array, bias light is projected through the rear surface of the substrate to introduce the background charge.

    Abstract: A compact, easily tunable, silicon avalanche diode oscillator for pulsed operation in the L-band which has an efficiency of about 40 percent, equal to that of vacuum tube oscillators operating at these frequencies, is obtained by utilizing a coaxial line composed of three serially connected sections in which the intermediate section has a characteristic impedance significantly larger than either of the other sections. One end of the coaxial line is short circuited; the avalanche diode is coupled to the coaxial line at a point between the short circuit and the beginning of the intermediate section; a variable capacitance is connected across the intermediate section at a given point thereof; and the other end of the coaxial line is connected to the output of the oscillator. The short circuit is made movable with respect to the position of the avalanche diode and the variable capacitance is made adjustable.
