Opportunity: Increase in the adoption of thermography for infancy stage diagnosis in healthcare applications

Clinical Thermography (CT) or thermal imaging is a non-invasive screening and diagnostic technique, which is combined with mammography or other scanning or diagnostic tool. Clinical thermography uses thermal cameras for infancy stage diagnose of cancer, infections, injuries, or vascular disease. It is one of the best preventive health assessment techniques, in which thermal cameras produce images based on the amount of heat dissipated by the human body. The images display heat patterns, thermal imbalances, and inflammation produced by blood circulation problems in the human body. This thermal imaging is also used in mass fever screening, neurological disorders, and breast cancer screening. Breast cancer is one of the common cancers diagnosed in women universally. Medical thermal imaging used to diagnose breast cancer is gaining momentum as it is a non-invasive and low-cost technique.

Challenge: Thermal cameras do not work through glass and water

Thermal cameras detect heat energy dissipated by the human body, animal, or any structure. The camera produces heat patterns and an image based on them, which helps investigate defects, threats, or other possibilities. Thermal imaging cameras do not work through glass and water because glass allows visible light to pass through it, but it acts as a mirror for thermal wavelengths. If a thermal camera is held in front of the glass, it will produce an image of the person holding the thermal camera. The image produced will be a blur and will lack significant detail and contrast.

Currently, high-tech autonomous vehicles, driverless vehicles, or Advanced Driver-Assistance Systems (ADAS) are gaining momentum in the automotive industry. In these vehicles, drivers are replaced by multiple sensors, including Light Detection and Ranging (LIDAR) sensor, Radio Detection and Ranging (RADAR), proximity sensor, and thermal cameras to aid automatic driving, navigation, and enhanced situational awareness. Thermal imaging cameras are integrated into driverless vehicles to improve night vision and detect pedestrians or animals in cluttered environments, misty, and foggy conditions, and automatically stop the vehicle to avoid any casualty.
