NIT MAGIC Described

OptoIQ reports that camera vendor Imaging Development Systems (IDS; Obersulm, Germany) announced it uses the MD1-10-B Logarithmic sensor from New Imaging Technologies (NIT; Evry, France) in the design of its latest high-dynamic-range (HDR) uEye camera. With a dynamic range of 120 dB, the camera features a 768 × 576-pixel imager in a 1/1.8-inch format, operating at 50fps.

Matrice Active à Génération d’Image indexée sur Contraste (MAGIC) sensor developed at NIT uses a pixel design based on a photodiode operated in photovoltaic mode so that the open-circuit voltage across the pn junction is proportional to a logarithmic value of the incident light intensity. To remove FPN there is a MOS transistor connected across the photovoltaic photodiode. When activated, this MOS transistor zeros the voltage of the photodiode under illumination and gives an exact dark reference voltage, used to remove FPN later on.

The same article tells that another camera vendor Point Grey Research (Richmond, BC, Canada) teamed up with CMOSIS (Antwerp, Belgium), embedding the company’s 1-in., 5.5 × 5.5um, 2048 × 2048-pixel, 170-frames/s CMV4000 and 2/3-in., 5.5 × 5.5um, 2048 × 1088-pixel, 340-frames/s CMV2000 into its line of Gazelle Camera Link cameras.
