In 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 measuring continuously at 6.6 kHz. This sensor can be exploited in applications in harsh environments where the size of the sensor is challenging.

Abstract
In 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 measuring continuously at 6.6 kHz. This sensor can be exploited in applications in harsh environments where the size of the sensor is challenging.File in questo prodotto:
