CONT

A number of publications by various groups have recently described halftone screen preprocessing techniques for achieving nonlinear nonmonotonic amplitude or irradiance transformations in coherent optical systems.... The two basic steps to the procedure include(1) an optical pulsewidth modulation to convert the continuous level input to an ideally binary halftoned input and(2) selection of various diffraction orders in the Fourier plane of a coherent optical processor to produce the continuous desampled output.

CONT

The gyros are used to maintain the platform's inertial orientation by sensing rotations of the platform caused by vehicle-rotation-induced friction at the gimbal pivot points... One gyro-called the vertical gyro-is oriented so its input axes are aligned with the X and Y platform axes; its input axes provide IMU [Inertial Measurement Unit] platform roll and pitch stabilization. The second gyro is oriented so that one input axis lies along the platform's Z axis and the other lies in the X-Y plane. This gyro-the azimuth gyro-provides platform yaw stabilization with the Z input axis, while the second input axis is used as a platform rate detector for built-in test equipment.

CONT

The sensors for angular velocity are vibrating gyroscopes (3 axes, to detect rotation and pitch/roll pendulations of the payload). An error signal is obtained differencing the signal from the azimuth gyroscope and a constant level settable from the telemetry, which controls the speed of rotation. Such error signal drives an analog PID [Proportional Integral Differential] circuit; the output of the PID is connected to the PWM [Pulse Width Modulation] driver supplying current to the pivot azimuth motors.

CONT

The bandwidth of a parallel-plate lens can be increased by a method of compounding lenses into a doublet. We can make a lens by using a uniform waveguide length between the input and output surfaces and placing a phase shifter in each line to compensate for the optical path-length differences and produce an eikonal at the aperture plane.
