Broadband close shot ultraviolet imaging spectrum device

Abstract

The invention provides a broadband close shot ultraviolet imaging spectrum device which is used for solving the problem that an existing ultraviolet imaging spectrum device can not flexibly detect an object within a wide ultraviolet spectrum range, and relates to the field of photoelectricity. The broadband close shot ultraviolet imaging spectrum device comprises a scanning portion, a front imaging portion, an interfering portion, a relay imaging portion and a detecting portion, wherein the scanning portion is used for scanning a tested sample according to a preset step length, the front imaging portion is used for conducting zooming and focusing on reflection light in a reflection mode, the reflection light is generated each time when the scanning portion conducts scanning, the interfering portion is used for conducting imaging on the reflection light, coming from the front imaging portion and generated each time when scanning is conducted, to form a first image and a second image, the content of the first image and the content of the second image in the same set are the same, the difference between the phase of the first image and the phase of the second image is a preset phase, the relay imaging portion is used for conducting superposition and interference on the first image and the second image in each set in a reflection mode to form a third image, and the detecting portion is used for converting optical signals of each third image obtained through superposition and interference into electric signals and conducting data processing.
