The optical system includes a plurality of optical subsystems and a plurality of reflectors. Each of the optical subsystems has an input aperture and is arranged to image light from the light source, the subsystems forming a spatial distribution of source images whose relative positions are different from the relative positions of the input apertures. Each of the optical subsystems further includes a plurality of reflectors disposed at the relative positions of the source images. Each of the reflectors is arranged to reflect light from a respective one of the subsystems onto the spatial light modulator.

摘要： An optical device which is suitable for use in a projection display comprises a spatial light modulator, such as a liquid crystal device, with a microlens array disposed on its front surface. The microlenses are of convergent type, such as lenticules. The spatial light modulator is of the reflective type and comprises a plurality of rear reflectors, each of which has convergent optical power in at least one direction. The reflectors are arranged such that, for a given direction of illumination, each reflector forms an image of the aperture A of a microlens on the aperture B of another microlens or at a different position on the same microlens. When used in, for example, a projection display, light losses caused by vignetting are reduced.

摘要： A cholesteric film is formed into an optical device comprising a plurality of layers. The cholesteric film is initially placed in a first predetermined state, for instance heating to a first predetermined temperature, and is then irradiated with narrow band UV radiation. The properties of an upper layer of the film are fixed, for instance for reflecting normally incident infrared radiation of a particular handedness. This process is repeated for different wavelengths of UV fixing radiation so as to penetrate to different depths from the surface of the film in order to form the layers. This method may be used to produce a filter of reduced sensitivity to angle of incidence. In addition to the infrared reflecting layer, red and green reflecting layers are provided. For normally incident radiation, the red and green layers reflect red and green parts R and G, whereas the blue part B of the spectrum is transmitted. For off-axis illumination or viewing, the red part R is reflected by the infrared layer and the green part G is reflected by the red layer. The birefringence of the infrared layer and the red layer reverses the direction of circular polarisation of the blue part B, which thus passes through the green layer.

摘要翻译：胆甾型薄膜形成为包括多层的光学装置。胆甾醇膜最初放置在第一预定状态，例如加热到第一预定温度，然后用窄带UV辐射照射。膜的上层的性质是固定的，例如用于反射具有特定手感度的正常入射的红外辐射。对于不同波长的UV固定辐射重复该过程，以便从膜的表面渗透到不同的深度以形成层。该方法可以用于产生对入射角降低的灵敏度的滤光器。除了红外线反射层之外，还设置红色和绿色反射层。对于正常入射的辐射，红色和绿色层反射红色和绿色部分R和G，而光谱的蓝色部分B被透射。对于离轴照明或观察，红色部分R被红外层反射，绿色部分G被红色层反射。红外层和红色层的双折射反转蓝色部分B的圆偏振方向，从而穿过绿色层。
