Types ofdeformable mirrors

Yes, and I did the calculations using that formula in my last post. The answer is wrong. I get different angle than 0.057.

The world is ready to see images at levels of detail never seen. Read more about the many places deformable mirror technology is used.

The ADXL335 datasheet does not mention the word "linear", but it specifies the sensitivity in units of mV/g. 1650.8 mV = 0.057°; 2450.8 mV = 91.63°

The thing is that wixey digital gauge has following specs. Range: +/- 180 degrees Resolution: 0.1 degrees Accuracy: +/- 0.2 degrees How can I specify my system in the same way as wixey did ? I tried the following approach. Please tell me that  am I on the right track. The thing is that I am using ADXL335B with 12 bit ADC. My power supply is 3.3V and Aref = 5V. I am doing single axis tilt calculations. The data sheet of the sensor is as follows http://www.analog.com/media/en/technical-documentation/data-sheets/ADXL335.pdf My calculations are as follows Desired Range = 0 to 180 degrees. 1. ) Resolution : 3.3 / 4096 = 0.8 mV 2.)  ADC_out =  ((3.3) / 5 ) x 4096= 2703.363)  (1.99-1.65) = 0.34   ; 1.99 corresponds to 90 degree and 1.65 V correspond to 0 degree. 0.8mV / 90  = 0.008 mV / degree But  i am lost here. what is the angle resolution in degrees? How can I calculate the accuracy of my system? The thing is that I also found the following paper on page 2. It uses arcSin() to calculate the angle resolution http://www.nxp.com/files/sensors/doc/app_note/AN3107.pdf It calculates the resolution in a different way and I get confused which method is correct.

Your desire to push the limits shouldn't be hampered by not having the latest information. Let us connect you with the right people who can help you choose the best deformable mirror for your system so you can focus on moving your discovery forward with adaptive optics.

Hi, I am using MSP430F5438A and learning about accelerometer interfacing. I am trying to do the single axis tilt meter using ADXL335B.
