Laser-Induced Graphene for Flexible and Embeddable Gas Sensors
ACS Nano, 2019 Laser-induced graphene (LIG) has received much attention since it enables simple and rapid synthesis of porous graphene. This work presents a robust direct-write LIG-based gas sensor, which senses gases based on thermal conductivity, similar to a ...

Short-range contactless laser sensor
2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017In this paper is shown all the process is needed to build a laser sensor, developed specifically for very short distance with a very compact size. Only the laser chip, a red VCSEL laser without any lens, makes the sensor. Features of this contactless sensor is a dynamic of measurement of 3 mm starting at 2 mm up to 5 mm with a resolution of 10 μm ...

Abstract After the operating principle of laser printers has been outlined using the Siemens Laser Printer ND 2 as an example, some of the typical sensors in such printers are described. The embodiment of these sensors in the printer concept, their physical functioning and the utilization of the available measuring options are described.

An eye safe Ho:YAG laser operating cw at 2.09 micrometers was used as the transmitter for this laser radar (ladar) system. The diode pumped Ho:YAG laser provided up to 100 mW of single frequency output power. An InGaAs detector was selected as the off-set homodyne receiver for vibration signatures. This paper describes the design and characteristics of

Review of Open Cavity Random Lasers as Laser-Based Sensors
ACS Sensors, 2022In this review, the concept of open cavity lasing for ultrasensitive sensing is explored, specifically in driving important innovations as laser-based biosensors─a field mostly dominated by fluorescence-based sensing. Laser-based sensing exhibits higher signal amplification and lower signal-to-noise ratio due to narrow emission lines as well as high ...
