    Abstract: A spectrum measurement apparatus includes: a plurality of light sources configured to emit light having different wavelengths to an object; a light detector configured to receive light, which is reflected or scattered from or transmitted through the object, and to measure an intensity of the received light; and a processor configured to determine a strength of an electric signal to be applied to at least one of the plurality of light sources by using one of the plurality of light sources, and by applying the electric signal having the determined strength to the plurality of light sources to obtain a spectrum of the object.

    Abstract: The invention relates to an image generation device comprising a laser light source (1); a mirror assembly having two parabolic mirrors (3, 6) via which a scanning light beam (1a, 5) generated by the laser light source is directed onto a sample surface (9); a deflection device (2), in particular a micromirror scanner, which is controllable such that the scanning light beam (1a, 5) scans points of the sample surface in a targeted manner; and a detector (10) which detects radiation emanating from a scanned point of the sample surface. The spatial resolution of the image generation device is substantially defined by the narrowest possible focusing of the laser beam, and the accuracy of the adjustable deflection angle is defined by the micromirror scanner.
