Characteristics and performance of a novel optical recording material in which information is recorded by surface deformation are described. This deformation recording material (DRM) has a high sensitivity (0.5 NJ/U2) independent of wavelength and adapted for use with a low-power He-Ne or diode laser. As opposed to ablative-type material, DRM type gives(More)
We present a high-bandwidth Hartmann-Shack sensor for adaptive optics implemented in a standard 0.35 /spl mu/m CMOS process technology. Hartmann-Shack sensors reconstruct an optical wavefront from the displacement of focal points as imaged by a microlens array. This image is usually captured by CCD cameras and then processed by software, limiting the(More)
The basis for most laser applications in neurosurgery is the conversion of laser light into heat when the incident laser beam is absorbed by the tissue. Irradiation of neural tissue with laser light therefore leads to its thermal damage. However, due to the diffusion of heat energy into the surrounding tissue, often there is thermal damage to neural tissue(More)
