In order to obtain the spectral images of objects with small scale, a method of hyperspectral microscopic imaging based on the image plane interferometry is proposed. The interferometric imaging system with microscope objective, collimating lens, lateral shearing beam splitter, imaging lens and detector is researched. An adjustable solid structure of the lateral shearing beam splitter is adopted and rotated to achieve the interferogram of the object. The microscopic imaging principle, magnification, spatial resolution, spectral resolution and depth of field are analyzed. An experimental prototype is constructed to carry out experiments on the epidermis of broad bean leaves specimen, and the spectral images in visible band are recovered. Experimental results validate the good performance of the system with high throughput and high spectral resolution, and show that a new method for the microscopic spectral imaging is provided.
