摘要： An LCD projector which has a white light source for emitting a randomly polarized luminous flux, and a plurality of LCD panels for modulating luminous fluxes that are transmitted through the LCD panels. The LCD projector also includes four reflecting devices. The first reflecting device reflects a first portion of the luminous flux having a first polarization characteristic and a wavelength which is within a first predetermined range of wavelengths, to the first LCD panel. The second reflecting device reflects a second portion of the luminous flux that is not reflected to the first LCD panel, to the second LCD panel. The second portion of the luminous flux has the first polarization characteristic and a wavelength which is within a second predetermined range of wavelengths. The third reflecting device reflects a third portion of the luminous flux that is not reflected to the second LCD panel, to the third LCD panel. The third portion of the luminous flux has the first polarization characteristic and a wavelength which is within a third predetermined range of wavelengths. The fourth reflecting device reflects a fourth portion of the luminous flux that is not reflected to the third LCD panel, to the fourth LCD panel. The fourth portion of the luminous flux has a second polarization characteristic.

摘要： An apparatus for isometrically splitting a reference light beam into a plurality of equally split beams. The apparatus includes a plurality of beam splitters having identical reflectance and identical transmittance. The beam splitters are arranged so that the split beams are transmitted through an equal number of beam splitters and reflected by an equal number of beam splitters to obtain split beams having identical characteristics.

摘要： A device including a polarizing beam splitter by which an incident luminous flux is split into a first luminous flux radiated onto a first photo sensor and a second luminous flux radiated onto a second photo sensor, and an adjusting mechanism provided for rotatably adjusting a position of one of the first and second luminous fluxes. The optical axis of the first luminous flux is coincident with that of the incident luminous flux. The optical axis of the second luminous flux is not parallel to the first luminous flux. By rotating the beam splitter about the optical axis of the first luminous flux, the beam receiving position of the second photo sensor, onto which the second luminous flux is radiated, is changed.

摘要： A polarization and birefringence measuring device has an optical source which causes a wide polarized light beam to impinge on a specimen. A photodetecting sensor having picture elements in two dimensions detects a light beam containing information about the specimen. A analyzer is situated in front of the photodetecting sensor and rotated to vary the amount of light which is transmitted. A frame memory memorizes the intensity of each picture element in the photodetecting sensor, and a computer determines the polarization state of parts of the specimen coresponding to the intensity of each picture element sampled. The computer samples the output of the photodetecting sensor when the rotation angle of the analyzer has reached a specified value, and this is memorized by the frame memory. As it may be assumed that the intensity variation of the light beam produced by the rotation of the analyzer is sinusoidal, its polarization state for each picture element can be found by performing no less than three measurements.
摘要翻译：偏振和双折射测量装置具有引起宽偏振光束撞击样本的光源。具有二维图像元素的光电检测传感器检测包含关于样本的信息的光束。分析仪位于光电检测传感器的前面并旋转以改变传输的光量。帧存储器存储光电检测传感器中的每个像素的强度，并且计算机确定对应于每个被采样的像素的强度的样本的部分的偏振状态。当分析仪的旋转角度达到指定值时，计算机对光电检测传感器的输出进行采样，并由帧存储器存储。由于可以假设由分析仪的旋转产生的光束的强度变化是正弦的，所以通过执行不少于三次的测量，可以发现每个像素的偏振状态。
