Abstract: Broadband pulsed light from a broadband pulsed light source is pulse-stretched such that an elapsed time and a wavelength in a pulse correspond to each other on a one-to-one basis, and is radiated to an object. The light transmitted through the object is received by a light receiver and converted into a spectrum by a calculator. The broadband pulsed light is divided according to a wavelength by dividing elements, and is pulse-stretched by two fibers having different dispersion characteristics or received by two light receivers having different characteristics.

Abstract: Methods and systems are provided for separating polarized UV light. In one example, a method may include passing polarized source light through a group of at least four prisms to collimate and separate a second-harmonic generation (SHG) beam from a pump beam. The separated SHG beam may then be further passed through a spatial filter to reduce spatial distribution.
