Title: Liquid crystal optical element
Inventor: ENDO HIROYUKI
IPC: G02F1/137
Filed: 1989-04-28
Abstract: PURPOSE:To obtain the liquid crystal optical element which does not require oriented films, has distinct bistability and allows the formation to a larger area by increasing the tilt angle in the ferroelectric phase of a liquid crystal material. CONSTITUTION:The liquid crystal material constituting a liquid crystal layer 4 is a ferroelectric liquid crystal material contg. a high-polymer liquid crystal and the tilt angle in the ferroelectric phase, i.e. chiral smectic C phase is adjusted to >=15 deg.. The stability in the respective bistable states of the liquid crystal molecules is not so good and the liquid crystal molecules are moved in opposite directions by the oscillation of heat or the like if the tilt angle thetais below 15 deg.. The poor bistability is resulted in such a case. The distinct bistability is obt. if the tilt angle theta is >=15 deg.. The oriented films for the liquid crystal are not particularly provided in the parts where the liquid crystal layer 4 come into contact with electrodes 3 to prevent the bistability from being impaired by the oriented films. The need for the oriented film is eliminated in this way and the formation to the larger area is possible. The liquid crystal optical element having the distinct bistability is obtd. in this way.

IPC: G01B11/06
Filed: 1983-06-16
Abstract: PURPOSE:To obtain highly accurate measuring value by making incident light with a prescribed incident angle interfare multiplly in a thin film, determining the number of degrees of interference temporally from a series of wavelength having the maximum value of a spectral transmission factor or a spectral reflection factor and repeating operation. CONSTITUTION:Light is made incident to a light tramsmitting thin film TL formed on a base substrate BS with a prescribed incident angle theta. A series of wavelength lambdai (lambdai<lambdai+1 for i=1-N, N>=2 and 1-N-1) having the maximum value of the spectral transmission factor or the spectral reflection factor is measured by making the incident light interfare multiply. The positive integer mj which is closest to K which satisfies K=lambdaj+1/(lambdaj+1-lambdaj) is temporally determined as the number of degree of interference of light having lambdaj wavelength. In the same manner, the number mi of degrees of interference of each wavelength is temporally determined and di is calculated on the basis of the formula ( I ). The temporal determination and operation of mi are repeated by substituting mj+ or -1, mj+ or -2, etc. instead of mj, plural pairs of di are obtained and the film thickness (d) is determined from the pair of the coincident di.
