A method of operating an anti-phase six degree-of-freedom tuning fork gyroscope system comprises the steps of driving a first three degree-of-freedom gyroscope subsystem, and driving a second three degree-of freedom gyroscope subsystem in an anti-phase mode with the first gyroscope subsystem at an anti-phase resonant frequency. Acceleration or an angular rate of motion is sensed by the first and second three degree-of-freedom gyroscope subsystems operating in a flat frequency response range where the anti-phase resonant frequency is designed. Response gain and phase are stable and environmental and fabrication perturbations are avoided by such operation. A anti-phase six degree-of-freedom tuning fork gyroscope system which operates as described is also characterized.

Real time, high-speed image stabilization with a retinal tracking scanning laser ophthalmoscope (TSLO) enables new approaches to established diagnostics. Large frequency range (DC to 19 kHz), wide-field (40-deg) stabilized Doppler flowmetry imaging is described for human subjects. The fundus imaging method is a quasi-confocal line-scanning laser ophthalmoscope (LSLO). The retinal tracking system uses a confocal reflectometer with a closed loop optical servo system to lock onto features in the ocular fundus and automatically re-lock after blinks. By performing a slow scan with the laser line imager, frequency-resolved retinal perfusion and vascular flow images can be obtained free of eye motion artifacts.

A data slicer circuit for extracting data from a received analogue signal having a preamble and a data portion with the data. The circuit comprises a low pass filter for obtaining a DC value of the received signal, and a comparator for comparing the received analogue signal to the DC value of the received signal. In dependence on the comparison of the received analogue signal to the DC value of the received signal, the comparator generates a digital bit stream. A filter for rejecting the preamble frequency receives analogue signal and feeds a filtered signal to the low pass filter. By rejecting the preamble frequency, before or after, the low pass filter a shorter settling time can be obtained.

An amplifier circuit includes first (7A) and second (7B) operational amplifiers connected in a generally parallel configuration, each with inputs coupled through the same pair of matched input resistors which receive a differential input signal that may have both a positive and negative common mode range. An offset adjustment amplifier (17) receives a differential error signal representative of the difference between offset voltages of the first and second operational amplifiers and generates offset adjustment signals that are applied to input stages of the first and second operational amplifiers to adjust their respective offset voltages so as to equalize them.

Provided are an optical display device manufacturing system and an optical display device manufacturing method which can more preferably carry out a defect inspection. A detection condition of a defect in the inspection of an optical film before being bonded to an optical display unit carried out by a defect inspection apparatus (14, 24) is corrected based on the result of inspection of the optical display device with the optical film bonded, carried out by an inspection apparatus (30), and the optical film including the defects detected by the defect inspection apparatuses (14, 24) based on the corrected detection condition are excluded.
