Abstract: Color information obtained by an optical sensor of a stylus can be displayed at a pen tip of the stylus with good visibility, and visual feedback is provided as a suitable user interface when the color information is transmitted from the stylus to an electronic apparatus. A stylus includes: a trigger signal generating circuit; an optical sensor that detects incident light; a memory circuit that stores color information of the incident light detected by the optical sensor; a color presenting circuit which is disposed at a pen tip of the stylus and which presents a color corresponding to the color information; and a control circuit. The control circuit presents the color information detected by the optical sensor using the color presenting circuit at the pen tip, and controls the color presenting circuit in response to a trigger signal from the trigger signal generating circuit when transmitting the color information to the electronic apparatus.

Abstract: An actively Q-switched laser induced breakdown spectroscopy (LIBS) probe, utilizing an optical fiber, a pump beam transmitted through the optical fiber, a coupler, and a lens for collimating the pump beam. The actively Q-switched laser, coupled to a sensor which provides information to a computer that controls a high voltage pulser providing a pulse to a Pockels cell located within the laser which can selectively cause the laser to pulse, resulting in high energy pulses and a second lens for focusing the output pulse such that it creates a plasma or spark. The light from the spark is captured and directed back through an optical system to remote equipment for elemental and/or molecular analysis.
