A2 Photonic Sensors' innovative approach is based in particular on the integration of miniature, highly performing, optical elements in its measurement systems, through the use of glass microtechnology. Through these sensors our aim is to give you access to characteristics that are uncovered or only partially covered by other technologies or systems (such as extremely dense flows, viscous sub-layers, …)

Main characteristics

B-POP

Bubbly flows
(bubble, slug, gas inclusion
of any shape)

• Concentration, velocity & size
• Flux, local flow rate
• Diameters (D10, D32)

Works in extremely dense flows
(0 to 100 % void fraction)

S-POP

Spray & atomization
(droplet, wave, liquid inclusion
of any shape)

• Concentration, velocity & size
• Flux, local flow rate
• Diameters (D10, D32)

Works in extremely dense sprays
(0 to 100 % local concentration)

i-LDA

• Aero & hydrodynamics
• Viscous sublayer
• Micro-fluidics & micro-channel

• Fluid & particle velocity
• Wall shear stress

• Very short focal length: 0 to 500 μm
• Miniature & non-intrusive sensor
• No adjustment nor calibration

IceCube

• Radiative transfer calculations
• Remote sensing validation
• Snow chemistry

Specific surface area of snow
