ABSTRACT:
Optically readable radiation-displacement conversion devices and image-rendering apparatus that incorporate same are disclosed. Also disclosed are related methods for detecting images and rendering images using such devices and apparatus. Such devices, apparatus and methods allow improved accuracy and sensitivity of radiation detection without having to use a cooler. A representative conversion device includes a substrate and a suspended portion attached to the substrate via a leg portion. The conversion device includes a radiation-absorbing film that receives and absorbs and incident invisible radiation (e.g., UV, IR, or X-rays) and generates heat from the absorbed radiation. The suspended portion includes a displaceable member that exhibits a displacement with respect to the substrate. The displacement also imparts a change to an incident readout light flux in accordance with the magnitude of the displacement. The change to the readout light is detected and used to form an image.
