Linear CCD driver

درایور V16 رسااندیشان برای CCDهای 5 ولت و پایین‌تر ساخته شده است. با این درایور CCD‌های مختلف از برندهای سونی، توشیبا، هاماماتسو، NEC و ON Semi راه‌اندازی شده‌اند. بسیاری از سازندگان تجهیزات اسپکتروسکوپی این نسخه را جایگزین آشکارسازهای قبلی خودشان کرده‌اند و از کیفیت بالای آن بسیار راضی بوده‌اند. هم‌اینک رسااندیشان نسخه V17 را نیز برای CCD‌های 12 تا 15 ولت طراحی کرده است. برای مشاهده انواع the company's CCD drivers, see the Line Scan Camera menu.

What exactly does a linear CCD driver do?

A linear CCD driver is an electronic interface circuit. It converts the analog pixels of a linear sensor into digital data. It then applies exposure time, signal gain, zero-level offset and digital filters. Finally, it sends the data to the computer so the image can be displayed in the software.

CCD sensor, does not give you an image on its own. The quality of the driver determines how much of the sensor's capability reaches you. That is why makers of spectroscopy equipment pay close attention to driver quality.

Linear detectors have a wide range of uses. Solar sensors, barcode readers, scanners and spectroscopy are some of them. Systems that measure thickness, distance, speed, angle, color, vibration and light intensity also use them.

There are two groups of noise in driver circuit design. The first group arises in the sensor itself. Reset noise, shot noise and dark noise belong to this group. The second group comes from the readout circuits outside the sensor. White noise, flicker noise and analog-to-digital conversion noise belong to this group. Dark noise depends strongly on temperature. The best way to reduce it is to cool the sensor.

The V16 driver is built for CCDs that run at 5 V or less. If your sensor runs at 12 to 15 V, go for the V17 version.
