Digital Holography as Computer Vision Position Sensor with an Extended Range of Working Distances [PDF]
Sensors, 2018 Standard computer vision methods are usually based on powerful contact-less measurement approaches but applications, especially at the micro-scale, are restricted by finite depth-of-field and fixed working distance of imaging devices.
