Hardware Information

• Laser illuminator

The illuminator uses an 830nm laser diode. Output power measured at the illuminator output is around 60mW (Using Coherent Lasercheck). The laser is temperature stabilised with a small peltier element mounted between the illuminator and the aluminium mounting plate. This element can both heat and cool the laser to maintain a constant temperature, presumably in order to stabilise the laser's output wavelength. on the sample tested, at room temperature, the laser is being slightly heated.

The depth sensing appears somewhat sensitive to the relative position of the illuminator and sensor. Even a gentle bend of the aluminium plate causes significant disturbance of the depth image.

• Depth Image sensor

The depth sensor uses a monochrome image sensor. Looking at the signals from the sensor, resolution appears to be 1200x960 pixels.
