30 News 2020 Vol.1 Empowering Breakthroughs with Light at Photonics West 2020 For LiDAR, there were two demonstrations focused on distance measurement using photon counting, featuring our newest MPPC PCI (photon counting image sensor) products. The first demonstration for distance measurement was based on the direct TOF (time-of-flight) method using a 16-channel 1D MPPC PCI and a pulsed laser diode. This demonstration showed that measurement is possible with a distance resolution of 7.5 mm (time resolution: 50 ps). The second demonstration measured distance by using a 32×32 ch 2D MPPC PCI. The distance was calculated by the time gap between the laser output and the reflected light, and the displayed color changed according to the distance information. In addition to this, a dedicated counter for LiDAR products hosted another demonstration which compared detectors; APD, MPPC, and SPPC, by projecting the differ­ ence of output waveforms by ND filter, bandpass filter and aperture. For industrial, three demonstrations showcased how our photonic products can be used in the areas of laser scanning, SWIR imaging, and gas analysis. The 2D raster scan demonstration showed the ability to scan various laser patterns using the integrated 2D raster MEMS mirror. The laser scanned horizontally at high speed, from the upper-left corner to the lower-right corner of a screen. Another demonstration featured SWIR imaging, which is widely used in non-destructive inspection for semiconductor, agriculture, food packaging, and all kinds of security purposes. The demonstration At this year’s Photonics West, exhibition attendees saw how Hamamatsu’s products empower breakthroughs with light. In the center of our booth, a special display area hosted demonstrations showing how our photonic technologies can be used in real-life applications, such as LiDAR, Industrial and Analytical. showed how our SWIR InGaAs cameras and image sensors can be used to distinguish defects and foreign contaminants by revealing wavebands that are typically invisible to our eyes. Our gas analysis demonstration showed how our infrared devices have the capability to provide real-time measurements of CO 2 con­ centration. The measurement of gas concentration can be vital to process control and preventative maintenance. For analytical, two demonstrations showcased how our photonic products can be used for the applications of mortar degradation analysis and plastic sorting. The demonstration for real-time on-site measurement using a port­ able device featured one of our newest products, the FTIR Engine (1100 to 2500 nm spectral range), designed for portable applica­ tions. Non-destructive degradation analyses of bridge and tunnel concrete are some of its many applications. The demonstration showed the results from using the FTIR engine to measure mortar (no air entrainment) degradation. Also there was a demonstration that showed how our MEMS-FPI module can identify the type of plastic or textile based upon its reflectance waveform. These demonstrations are only a sampling of what our products can do. We look forward to Photonics West 2021, where we plan to con­ tinue to showcase our newest photonic components and systems and how they can be used in various applications to ensure accurate mea­ surements, improve productivity, and empower more breakthroughs.
