Italian machine vision camera manufacturer Alkeria has announced CELERA One P as a new addition to the polarisation camera series, next to CELERA P.
Based on the single USB3 interface of the CELERA One cameras, CELERA One P gives the possibility to performing inspection processes with the same quality and features of CELERA P but in a convenient package. With a 5 megapixels polarisation Sony Pregius® IMX 264 sensor, CELERA One P, gets rid of all external polarizing filters thanks to the unique array of polarizer filters overlaid on top of the sensor’s pixel array, combining the ease-of-use of the Alkeria USB3 cameras with the advanced capabilities of polarisation imaging and unique FusionView feature.
CELERA One P can execute polarisation detection directly on-board, without overloading the computer, thanks to its powerful FPGA architecture.
With the special polarisation filter array applied on the sensor, each “superpixel” can acquire 4 different polarisation angles simultaneously. Based on the information acquired from these four channels, a special interpolation algorithm computes data for all the in-between angles, as if a rotating polariser had been put in front of a plain monochrome camera. This measure is the key to deriving complex parameters such as the Degree of Linear Polarisation (DoLP), an estimate of the polarisation coherency of the light, and the Angle of Linear Polarisation (AoLP), an estimate of the polarisation angle.
Since monochrome video format is not suitable to visualise AoLP and DoLP information simultaneously, we developed an advanced feature for our cameras: the FusionView feature. FusionView is a unique feature available only on Alkeria’s polarisation cameras: it maps AoLP on the Hue component of the HSV color space and DoLP on the Saturation component, giving an intuitive preview of these properties of light.
CELERA One P is equipped as standard with a C-mount lens adapter, also F-mount lens adapter is availble on request.
