The benefits of greater accuracy and throughput<\/a> from high-resolution cameras can only be realized if the entire image sensor is usable<\/a>. Metrology cameras<\/a> are optimized for uniformity and dynamic range among other parameters to provide the most accurate starting image. Metrology cameras are relied on when the pixel information is used as measurement input such as with process control systems for semiconductor and electronics manufacturing and others. <\/p>\n <\/p>\n <\/a><\/p>\n <\/p>\n Active Sensor Control (ASC) is Adimec\u2019s<\/a> toolbox for our metrology cameras<\/a> to achieve the most usable pixels and accurate data. It incorporates all of the functions used to tune the sensor for the specific needs of an application and measures to optimise imaging performance under the system conditions. There are three steps involved to ensure you get accurate input information from the camera for your measurement method.<\/p>\n <\/p>\n <\/p>\n <\/p>\n Step 1: Sensor Technology is characterized for optimized design and implementation<\/b><\/p>\n <\/p>\n Step 2: Sensor operation is tuned during production to minimize blemish generation, increasing the operational imaging range (DNR, uniformity)<\/b><\/p>\n <\/p>\n Step 3: Calibrate each camera to effectively manage remaining blemishes and non-uniformity responses through embedded corrections<\/b><\/p>\n <\/p>\n By minimizing the blemishes per individual camera we make sure the largest performance range results, and less severe corrections need to be done that can reduce the contrast range (DNR). All of the tunings involved are to guarantee the cameras consistently provide reliable image quality for accurate measurements.<\/p>\n <\/p>\n Related Blog Posts:<\/b><\/p>\n Detect smaller features with metrology cameras<\/a><\/p>\n <\/p>\n Ways to increase throughput in semiconductor and electronics inspection<\/a><\/p>\n <\/p>\n\n
