Abstract
A compact holographic SLM spectrometer without an optical diffraction element is provided. The compact holographic SLM spectrometer performs the basic spectrometer function using a spatial light modulator (SLM). The compact holographic SLM spectrometer includes a light source, an input element, a collimator, an SLM, an analysis and detection optics, at least one detector, and a digital and/or analog control device.
Claims41
A compact holographic spatial light modulator (SLM) spectrometer comprising
- a light source with spectrum,
- an input element, wherein the input element allows a light to enter a system,
- a collimator for aligning the light linearly,
- an SLM for shaping light in space,
- an analysis and detection optics, wherein the analysis and detection optics focuses a radiation, wherein a wavefront of the radiation is disrupted after the SLM,
- a detector for taking an image,
- a digital and/or analog control device for controlling at least one selected from the group consisting of the light source, the input element, the collimator, the SLM, the analysis and detection optics, and the detector configured in the system.
