    Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin 2 (mθ +π/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by corresponding filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

    Abstract translation: 用作空间辐射调制器的盘在其上具有分散的辐射滤波器。 每个滤波器具有形式为sin 2（mω+À/ 4）的透射率或反射率调制函数，其中m是正整数，p具有四个值0,1,2,3中的一个。包括选择的辐射束 波长分量被衍射成根据波长分散的细长图像。 不同的波长分量聚焦在调制器上的不同滤波器上，并由相应的滤波器编码。 由于滤波器的调制功能彼此正交，因此可以在一次测量期间从总检测信号对相应的滤波器进行编码或调制之后提取每个波长分量的振幅。

    Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin (m theta + p pi /4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by corresponding filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.
