摘要： PURPOSE:To reduce the size of a spatial optical modulator and eliminate the need for a combinational adjustment, and to operate it effectively as an information transmitter by modulating incident light from a remote light source by a material which has electrooptic effect, and reflecting the modulated light to the light source side in parallel to the incident light. CONSTITUTION:A light beam from a master station when made incident as incident light (a) is reflected by a point P on a reflecting surface 12, passed through liquid crystal 21 and reflected at a point Q on a reflecting surface 11, and passed through the liquid crystal 21 again to obtain reflected light (b). When, however, the light is passed through the liquid crystal 21, a voltage is applied between electrodes 22a and 22b by an information signal to transmit the reflected light (b) after optical modulation. Therefore, no light source is necessary on the side of this spatial optical modulator, and the information signal applied between the electrodes 22a and 22b of the spatial optical modulator is transmitted to the remote light source side. Thus, the efficiency of information transmission is improved. Further, this spatial optical modulator is provided with a reflecting plate and a modulator in one body, so there is no unnecessary space to attain the size reduction and the need for the combinational adjustment is eliminated.
摘要翻译：目的：为了减小空间光学调制器的尺寸，消除了对组合调整的需要，并且通过用具有电光效应的材料调制来自远程光源的入射光，并作为信号发射器来有效地操作它，并且反映调制与入射光平行的光源侧的光。构成：作为入射光（a）入射的来自主站的光束被反射面12上的点P反射，通过液晶21并在反射面11上的点Q反射，并通过液晶21再次获得反射光（b）。然而，当光通过液晶21时，通过信号信号在电极22a和22b之间施加电压，以在光调制之后传输反射光（b）。因此，在该空间光调制器的一侧不需要光源，并且将施加在空间光调制器的电极22a和22b之间的信息信号传输到远程光源侧。因此，提高了信息传输的效率。此外，该空间光学调制器在一体中设置有反射板和调制器，因此没有必要的空间来实现尺寸减小，并且消除了组合调整的需要。

摘要： PURPOSE:To improve the detecting accuracy for the position of a traveling object with no combination control by unifying a splitter, a total reflector and an optical demodulator. CONSTITUTION:For a space optical demodulator, a photodiode 13 is set at the front of a reflecting surface 11 which is orthogonal to a reflecting surface 12. These surfaces 11 and 12 have prism surfaces to reflect totally the light. A part of the incident light (a) is reflected on the surface of the diode 13 and sent toward a light source in parallel to the light (a), and the rest light (a) is put into the diode 13 and converted into an electric signal. Therefore such a space optical demodulator is set on a traveling object 5 to convert the optical signal sent from a control point into an electric signal. At the same time, a part of the optical signal is reflected and can be transmitted toward a position detecting part at the control point. In addition, the position of the object 5 is easily detected with improved accuracy since the reflected light (b) is approximate to the light (a) and reflected at the position extremely close to the light source.

CONSTITUTION:An optical modulator 1 modulates the light beams of a laser 2 with an information signal 3 and irradiates these modulated beams to a corner cube 4. A semi-transparent reflecting plate is provided to the cube 4 together with a photoelectric transducer attached to the rear side of the cube 4. Thus an optical demodulator 5 is obtained. In such a way, a part of the incident light is supplied to a signal processing circuit 6 after photoelectric conversion and demodulation. While the reflected light sent from the reflecting plate is reflected again by a reflecting plate set at the same cube 4. A modulator element made of a material having an electro-optical effect and containing an optical switch function is provided at the front of the reflecting plate. Thus an optical modulator 8 is formed. Thus the reflected light is modulated with an information signal 7 and reflected in parallel to the incident light. This reflected light is sent to an optical demodulator 9 to receive photoelectric conversion and then supplied to a signal processing circuit 10 after demodulation.
