Abstract:
1. A spectrometer configured for optical coherence tomography imaging, comprising: multiple inputs; input optics; a diffraction grating, wherein the diffraction grating is a transmission grating, and wherein the input optics comprise a collimating lens set that collimates light from the multiple inputs toward the diffraction grating; output optics; and a camera that is configured to image multiple lines at a rate of at least 1000 lines/second; wherein the light from the multiple inputs are is focused onto independent imaging sections of the camera using the same input optics, the same diffraction grating, and the same output optics, wherein: the multiple inputs comprise a first input and a second input; there is a first optical path from the first input to a first section of the camera; there is a second optical path from the second input to a second section of the camera; and the first optical path overlaps with the second optical path.
