Pisa, ITALY – April 12, 2024
Alkeria, Italian machine vision camera manufacturer, is pleased to announce the latest addition to its CELERA P camera series.
CELERA P, the world's first polarization camera to use the dual-USB3 technology, will now feature a 12-megapixel resolution Sony Pregius® IMX 253 sensor.
The adoption of this sensor allowed Alkeria to create the new model C12SX-MP designed, similar to the previous CELERA P models, to combine the ease-of-use of the Alkeria USB3 cameras with the advanced capabilities of polarization imaging and the exclusive FusionView feature.
Thanks to the special polarization filter array applied to the sensor, each superpixel can acquire four different polarization 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 polarizer 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 Polarization (DoLP), an estimate of the polarization coherency of the light, and the Angle of Linear Polarization (AoLP), an estimate of the polarization angle.
Since the monochrome video format is not suitable for visualizing AoLP and DoLP information, we developed an advanced feature for our cameras: the FusionView feature. FusionView is a unique feature available only on CELERA P: it maps AoLP to the Hue component of the HSV color space and DoLP to the Saturation component, giving an intuitive preview of these properties of light.
Thanks to the powerful FPGA architecture, CELERA P can execute polarization detection directly on-board without overloading the computer.
CELERA P is equipped as standard with a C-mount lens adapter. Also, F-mount lens adapter is available on request.
