Abstract

Aiming at the complex structure, difficult installation and high cost of the multispectral camera optical system used for phenological observation, a miniaturized and snapshot multispectral camera scheme is proposed. A compact and multi-channel image parallel optical system is designed by using a four-sided pyramid prism as an important optical element. The field-of-view of the system is ±3°, the working band is 400nm-600nm, the focal length is 50mm, and the F number is 5. The design results show that the single wavelength modulation transfer functions (MTF) at Nyquist frequency is better than 0.5, the root mean square radius (RMS) of all field of view is less than 7.4μm, and the distortion is less than 0.5%, which can meet the design requirements of multispectral cameras.
