CMOS Image Sensor
- Sunday, 01 March 2009
The MLX75307 CMOS image sensor from Melexis, Concord, NH, is designed for automotive front vision applications such as advanced driver assistance systems, high-beam assist, and night vision. It also can be used in medical and industrial applications. The sensor features a high-dynamic-range pixel matrix that extends the input and output dynamic ranges. It also feature a low-light response boost that increases image brightness and contrast in low-light conditions.
Using the EMVA1288 standard, the sensor’s 12-bit performance was limited by shot noise at ambient temperatures and to detect NIR light irradiance below 500 photons per pixel at a frame rate of 150 fps. This corresponds to detecting a candle at a distance of more than 250 m with a typical night vision lens.
