What are next generation bio sensing techniques? Part 2
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 […]
Laser module addresses applications in industrial sensing and measurement
EMCORE has introduced its Model 1790 1550 nm High-Power Laser Module for LiDAR and Optical Sensing. The 1790 was developed for use as a CW coherent optical source for next-generation FMCW LiDAR systems in autonomous vehicles and other optical sensing applications. A custom version of this product is being adopted by a major provider of […]
Matrox imaging lasers in with launch of 3D profile sensors
Matrox Imaging has announced the launch of the Matrox AltiZ, a series of integrated high-fidelity 3D profile sensors featuring a dual-camera single-laser design. These fully integrated 3D profile sensors have an optimized design that lessens scanning gaps. Simultaneous viewing of the laser line by the Matrox AltiZ’s two opposed optical sensors reduces optical occlusions — […]
What types of problems can fiber optic kinetic sensor solve?
At Sensors Expo 2019, Dennis Horwicz, Product Manager at Micronor explains how his company’s fiber optic sensors for mechanical motion applications can be used in challenging applications that include electromagnetic interference (EMI)/ radio frequency interference (RFI), radiation, high voltage, magnetic field, temperature extremes and even an explosive atmosphere. A fiber optic kinetic sensor to measure […]

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 […]
