摘要： The invention concerns a liquid crystal display device intended, in particular, to form a colour image display screen, of the type including: a first substrate which is transparent on a front side situated on the side of the viewer; and a second substrate arranged on a back side facing the first substrate and extending parallel to the latter. The first substrate is connected to the second substrate in order to delimit between them a cavity in which at least one film of liquid crystal is arranged. The liquid crystal has at least a first state in which it reflects the light of a range of wavelengths of a predetermined colour and at least a second state in which it is transparent. The surface of each substrate facing the other substrate includes electrodes to allow the liquid crystal to pass at least from the first state to the second state or conversely, by selective application of a control voltage to the electrodes. The liquid crystal display includes a filter absorbing at least the visible neighbouring wavelengths of the range of wavelengths of the predetermined colour and the closest to the wavelength 555 nm with the exception of the wavelengths of said predetermined colour. The filter is arranged on the side of the viewer with respect to the film of liquid crystal.

摘要： An optical device (20) is provided using at least one film (23) of cholesteric liquid crystal to reflect at least one predetermined wavelength band from an incident light. This device is characterized in that a non zero birefringence gradient is present in a portion or the entire thickness of said film. The gradient may be obtained in particular by superposing layers (24a-24j) having increasing or decreasing respective birefringence coefficients. The birefringence gradient has the effect of removing the lateral bands of the reflection spectrum, hence making the color of the reflected light more brilliant and more saturated. The effect is particularly advantageous in the case of the color red, for which the lateral band located on the yellow side is perceived strongly by the human eye.
摘要翻译：使用胆甾型液晶的至少一个薄膜（23）提供光学装置（20），以从入射光反射至少一个预定波长带。该装置的特征在于，在所述膜的一部分或整个厚度中存在非零双折射梯度。可以通过叠加具有递增或减少的双折射系数的层（24a-24j）来特别地获得梯度。双折射梯度具有去除反射光谱的横向带的作用，因此使得反射光的颜色更加明亮和更饱和。在红色的情况下，该效果特别有利，对于该颜色，位于黄色侧的横向频带被人眼强烈感知。

摘要： A lamellar grating interferometer is described, in which the light beams are collimated and focused onto the grating by means of mirror 9, which at the same time serves for collecting the light reflected from the grating. In this case, the light beam of a white light source 1 is first collimated by means of first lens 2, and subsequently passed through a sample cuvette 3. The transmitted light beam is subsequentlyy focused and coupled by another lens 2 into a fibre 17. The light to this fibre 17 is subsequentlyy directed towards a mirror 9, reflected from this mirror 9 onto a grating 11, which forms part of a lamellar grating interferometer which is realised by means of a micro electro mechanical device MEMS 7, which is mounted on a MEMS holder 6, as is the fibre 17. The light reflected from this grating 11 is reflected onto the same mirror 9, and focused and coupled by this same mirror 9 into a second multimode fibre 18, which is also fastened to the holder 6. The light guided by this second multimode fibre 18 is subsequently fed into a detection device 4.
