3 OUTLINE 1. Imaging for Industry

4 1. Imaging for industry Industry 4.0 strategies will become increasingly important. Factories of the future will bring automation to zero defect concept Better sensors and actuators will play a key role in FoFs. Machine vision techniques will optimize and accelerate many aspects of industrial manufacturing Industry is adopting machine vision as one of the main pillars for controlling and monitoring their processes in line / real time Infrared imaging is getting more a more important in machine vision for industry

5 1. Imaging for industry Industrial machine vision is led by VIS-NIR and thermal cameras SWIR and MWIR can be considered, until date, residual spectral bands in machine vision The reasons have been. purely technological?

6 1. Imaging for industry Volume Technologies ( before 2010) Silicon (VIS-NIR) Microbolometers (LWIR) In 2010 a new advance in sensor technology opened the MWIR spectral band to the industry VPD PbSe FPAs

7 1. Imaging for industry IR image sensors are semiconductors and volume refers to a technology ruled by Moore s law. Si CMOS compatibility = Monolithic integration = Volume New actor since 2010

8 1. Imaging for industry After 2010

9 1. Imaging for industry

10 OUTLINE 2. Industrial processes monitor and control

11 2. Industrial processes monitor and control Temperature assesment and heat dynamics are key parameters to be monitored and controlled in most industrial processes Non contact temperature assessment is always a complex task Infrared sensors have been used as primary technique for a long time. Excellent devices are now available. Most of them are single point / multipoint devices (single band, multiband etc.) specifically adapted and adjusted to a particular application However, even the technological advances have been impressive in camera sensors, still 2D temperature maps are much less accurate and reliable devices than point detectors.

12 2. Industrial processes monitor and control CCDs and CMOS cameras (Silicon) They are sensitive to temperaturas above 600 º C According Planck s law the devices sensitve to VIS-NIR spectral band are proned to face issues with the dynamic range in the high temperature ranges. Less accurate and/or get saturation CMOS MWIR Melt pool 2D relative temperature 2D maps Ref: Uncooled MWIR PbSe Technology outperforms CMOS in RT closed loop control and monitoring of laser processing OSA 2017 /AIMEN and Fraunhofer ILT Fast / snapshot Sensitive to atmospheric transmission issues Sensitive to issues related with low emissivity materials

13 2. Industrial processes monitor and control Thermal cameras (Microbolometers, VOx or a-si) They are sensitive in a wide range of temperatures above 0 º C 1500 ºC. Very extended in the industry but rarely used in closing control loop They suffer problems associated to the sensor dynamic range. Frequent changes in the camera parameters (integration time, ND filters etc.) which make difficult to apply radiometric corrections in a wide range of temperatures Slow devices / Rolling frame Limitations for implementing spectral capabilities for emissivity independent devices In general, it doesn t make sense to run microbolometers faster than about 30 fps FLIR Report

14 2. Industrial processes monitor and control MWIR cameras (VPD PbSe) They are sensitive in a wide range of temperatures above 100 ºC 2000 ºC Promising technology with high growth potential Huge dynamic range. No need changes in the camera parameters (integration time, ND filters etc.) in a very wide range of temperatures which make easy to apply radiometric corrections Very fast devices / snapshot Possibility of implementing spectral capabilities (emissivity independent devices) Ref: Temperature imaging in the MWIR range independent of emissivity SPIE 2018 / AIMEN

15 2. Industrial processes monitor and control Industry 4.0 is adopting Machine Vision techniques very fast Machine Vision Sensors have to be compliant with Industry requirements: Reliable and Affordable and Available As consequence sensor technologies suitable for Machine Vision have to be volume technologies = CMOS compatible and uncooled. VIS-NIR and Thermal cameras are volumen technologies and lead the Machine Vision industrial market In 2010 a new actor joined the club for Industrial Machine Vision: VPD PbSe. It is a quantum sensor which fills important gaps left by visible and thermal cameras: Very fast (2 orders of magnitude faster than termal cameras) and snapshot MWIR sensitive with spectral capabilities. Suitable for temperature assesment independent of emissivity Suitable for monitoring and controlling dynamic processes in real time
