英文摘要In order to solve the problem in traditional spectral imaging spectrometers that the spectral and image information cannot be acquired at the same time, a new type of real-time imaging spectrometer working in visible/ near-infrared wide spectral range is designed. Different from traditional push-broom imaging spectrometers, the system is with multi-slits imaging technology that the spectral image of target is divided into several areas to achieve large field of spectrum. The system reasonably adopts low-dispersion optical glass and doublet lens to achieve aberration correction among wide spectral range. The front telescope objective system is a combination of complex double Gaussian structure to achieve small distortion and uniform illumination at slits for different fields of view. The image of telescope objective system is divided into two parts by prisms, and high spatial resolution of video monitoring and high spectral resolution of spectrometer are obtained. One part is received by a high-resolution panchromatic camera and the other is received by a grayscale camera. Triplet prisms are used as dispersion components. By optimizing the angle of prisms and controlling the actual light, a coaxial optical path and dispersion linearity is achieved with CaFinf2/inf-silica-CaFinf2/inf structure. The results are as follows: spectral range of the optical system is 400~1000 nm, F number is 3.5, modulation transfer function (MTF) of distortion is lower than 0.1%, illumination uniformity at image plane is higher than 98%, and MTF of the front telescope objective system is more than 0.5 at the Nyquist frequency. The designed MTF of the optical system is more than 0.44 at the Nyquist frequency and spectral resolution is 10 nm. , 2015, Chinese Optical Society. All right reserved.
