Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]

High optical output laser diode targets LiDAR apps
ROHM Semiconductor announced they have developed a high optical output laser diode, the RLD90QZW3, for applications such as AGVs (Automated Guided Vehicles) and service robots in the industrial equipment sector and robot vacuums in the consumer field that incorporate LiDAR for distance measurement and spatial recognition. In recent years, LiDAR has been increasingly adopted in […]
What is the difference between an absolute and incremental position encoder?
Measuring the position of a rotating shaft, speed or direction of motion typically requires a rotary encoder. The two main types of encoding techniques are: absolute and incremental encoders. The absolute encoding technique provides a specific and unique position value for every point of rotation when it is switched on. Absolute encoding is commonly achieved […]

What position is this thing in?
Associated questions could include: Has it moved? In what type of motion? How close is it? While accelerometers, gyroscopes and magnetometers provide inertial measurement units (IMUs) for position sensing in smart phones and other portable products, many other sensing technologies have been used to determine position, long before the smart phone. In industrial applications, more […]
