Hello,
I am using Matlab 2012 with Image Acquisition Toolbox 2012.
I am using a generic webcam (Logitech Sphere AF) with the command
frame=getsnapshot(obj);
for image capture with the following default properties:
% % Device Specific Default Properties:
% BacklightCompensation = on
% Brightness = 128
% Contrast = 32
% Exposure = -7
% ExposureMode = auto
% Focus = 0
% FocusMode = auto
% FrameRate = 30.0000
% Gain = 0
% HorizontalFlip = off
% Pan = 0
% Saturation = 32
% Sharpness = 224
% Tilt = 0
% VerticalFlip = off
% WhiteBalance = 4000
% WhiteBalanceMode = auto
I am trying to find a faster camera model and property settings, if possible on a usb connection.
Does anyone have any suggestions for a specific camera model and associated manually configured properties settings for maximum frame capture speed?
Best, Jeremy

Jeremy,
We use the Thorlabs CMOS camera and get frame rates of several hundred Hertz using mex files, for regions of interest of 32 x 32 pixels. There is some memory management involved, and we use separate mex files for opening the camera (once per session), grabbing a frame, and closing the camera (once per session). We also have a mex file for setting the pixel clock, the exposure, and the frame rate. I don't promise it will work for you, but I've posted the files for the time being here, along with the code required to create the mex files and a demo m-file that tests it all out.
By the way, we also do SLM compensation through scattering media! Good luck.

Chris Stockbridge mentioned a File Exchange contribution; did you give that a try?

All of the files for working with the Thorlabs DCx series of cameras can now be found on the MATLAB file exchange here: Thorlabs DCx

How high are you aiming?
I would be almost certain this does not use a USB interface.
