Abstract: Disclosed is an optical pulse adjusting device including a pulse shaper that receives an input signal generated based on an optical frequency comb (OFC) signal and outputs a spectrum adjustment signal by adjusting an optical spectrum shape of the input signal, an optical amplifier that outputs an optical amplification signal by amplifying the spectrum adjustment signal, an optical spectrum analyzer (OSA) that outputs an information signal by comparing an optical spectrum shape of the optical amplification signal with a target optical spectrum shape, and a control circuit that outputs a comparison signal based on the information signal. The pulse shaper further receives the comparison signal and adjusts the optical spectrum shape of the input signal based on information about a difference between the optical spectrum shape of the optical amplification signal and the target optical spectrum shape, which is included in the comparison signal.

Abstract: Disclosed is an apparatus for obtaining an image. The apparatus for obtaining an image includes a light source, a scanner, a first beam splitter, and a light receiving unit. The light source generates a laser pulse. The scanner irradiates the laser pulse in a first direction. The first beam splitter splits the laser pulse irradiated in the first direction in the first direction and a second direction and irradiates the split laser pulse. The light receiving unit detects reflected light. Accordingly, it is possible to irradiate light to a wide range by a light source having a relatively small divergent angle.
