    Abstract: According to the present invention, an optical differential interrogation method for surface plasmon resonance imaging including: letting first incident light of a first wavelength and second incident light of a second wavelength to be incident on a sample while varying an incident angle; detecting intensity of first reflection light of the first incident light and intensity of second reflection light of the second incident light; and identifying the sample by using a difference between the intensity of the first reflection light and the intensity of the second reflection light, can be provided, and thus it is possible to obtain much better angular resolution while using a detector or a camera, which has a relative low receiving sensitivity and a sensor chip where samples having various characteristics are two-dimensionally arrayed and integrated can be effectively measured.

    Abstract: A laser emitter module may include a first laser emitter configured to output first laser beam having a first radiation angle by receiving first input laser beam and a second laser emitter configured to output second laser beam having a radiation angle different from the first radiation angle by receiving second input laser beam having a width different from that of the first input laser beam. The first and second laser emitters output the first and second laser beam together.

    Abstract: Disclosed are a next-generation lidar sensor apparatus that may acquire and process individual characteristic information about an object in addition to distance and shape information about the object, and a signal processing method thereof. According to the present invention, it is possible to accurately and quickly identify and track the object by adding a function of measuring unique material characteristics, such as a color and reflectance of the object, to the three-dimension image lidar sensor for measuring a position and speed of the object. In addition, when a plurality of lidar sensors are distributed on a space where measurable distances partially overlap with each other, it is possible to remove interference and naturally occurring noise between adjacent lidar sensor signals.

    Abstract: A photoacoustic sensing apparatus includes a light source that directs an optical signal toward an analyte, a photoacoustic sensor that receives an ultrasonic wave generated from the analyte and generates a photoacoustic sensor signal, and a signal processing device that controls the directing of the optical signal toward the analyte, and removes electromagnetic interference (EMI) noise from the photoacoustic sensor signal to generate a photoacoustic signal. A photoacoustic sensing method includes providing a first control signal to an optical switch connected to a light source to block or transmit the optical signal, generating a mixed signal that includes a photoacoustic signal and first EMI noise when the optical switch transmits the optical signal, and second EMI noise when the optical switch blocks the optical signal, and removing the EMI noise from the photoacoustic sensor signal based on the mixed signal and the second EMI noise.
