The image display apparatus includes a light detection apparatus in addition to a light source section, an illumination optical system, an optical modulation section, a spatial filter, a light projection section and a screen. The light detection apparatus detects the dispersion of a modulation characteristic of each pixel element of GLV devices and the ununiformity in luminance and color displayed in accordance with an illumination condition. An optimum driving voltage for minimizing the ununiformity in color and luminance to be displayed is determined based on a signal detected by the light detection apparatus.

摘要： A constant voltage supply unit having a high-speed load response, equipped with a fold-back type over-current protection function in which an output current detection voltage indicative of the output current is compared with the sum of a feedback voltage indicative of the output voltage and an offset voltage. The over-current protection function has a characteristic that the offset voltage is inversely proportional to the output-current detection voltage, so that the offset voltage is large when the output-current detection voltage (or the output current) is low, and decreases with the output-current detection voltage. In addition, the constant-voltage power supply unit allows enhance feedback of ac components in the feedback loop so as to enhance the ESR of the load-side capacitor, thereby securing phase compensation to prevent oscillations in the feedback loop.

摘要： For effecting auto-focussing of an objective lens used for observing a semiconductor wafer, a semiconductor microscopic device includes an inspection stage for supporting a semiconductor wafer and an objective lens for observing the semiconductor wafer. For automatic focussing of the objective lens, a defocussing magnitude of a light spot is detected using a knife edge. A collimator lens is oscillated by a voice coil motor to oscillate the light spot on the wafer. A peak value of the defocussing quantity detected at this time is peak-held to generate a position detection signal. The inspection stage is vertically moved so that this position detection signal will be equal to a pre-set target value.
