    摘要: A holographic reproducing apparatus capable of regulating aberration to a low level and suitable for reducing the size of the entire optical system is provided. When a forward meniscus lens is used for a converting lens 12 that collimates a reference beam L2, the converting lens 12 can be disposed between a light source 11 and the principal point Q of the converting lens 12 since the principal point Q of the lens is located at a position adjacent to a light-emitting surface 12a. With this, the distance between the light source 11 and a reflecting mirror 13 can be reduced, and thereby a reduction in the size of the optical system of a holographic reproducing apparatus 10 can be achieved.

    摘要: A capacitance detecting circuit includes a code generator for generating code having orthogonality in chronological order. A column-line driver drives the plurality of column lines based on the code by dividing the column lines into a first column line group and a second column line group. A capacitance detector, which is connected to the row line, converts the total of currents generated in capacitances at the intersections with the driven column lines into a voltage signal and outputs the converted voltage signal. A decoding computation unit determines the voltages corresponding to the capacitances at the intersections for each of the column line groups by performing product sum computation between the measured voltages and the code. The column-line driver drives the first column line group and the second column line group by complementary voltages according to the code or information indicating the inversion of the code.

    摘要: A remote coordinate designating device has a remote control with a light emitting device for emitting light, and a controller for detecting a designated position by receiving light from the remote control at a distance from the remote control. One cycle of a light signal from the light emitting device is composed of switch data and a coordinate detection timing header at the head, and a coordinate detection carrier. The switch data and the coordinate detection timing header use the same frequency as the normal remote control frequency band, and the frequency of the coordinate detection carrier is lower than the frequency of the switch data and the coordinate detection timing header. The switch data contains on-off information about a switch for pointing, and coordinate detection is started when a predetermined time has passed from the rise of a burst portion in the switch data.
