Physical Stereo Robot (PSR)

The PSR (Physical Stereo Robot) is a custom-built apparatus that allows us to present physical targets and assess depth magnitude. The stimuli used are mounted to the PSR system, which consists of motion stages within an enclosure. Observers are seated, and are required to place their head on a chin rest, allowing them to view the stimuli through an aperture situated at one end of the enclosure. Actuators that are mounted within the enclosure are motion controlled by motors. The stimuli moves along the motion stage as required.

Stereoscope (x2)

The stereoscopes used in our lab are Wheatstone stereoscopes. Each consists of a pair of angled mirrors set at 45-degree angles and a chin rest placed in front of them. The participant places their head on the chin rest. Each mirror projects a different image to each eye  (left image from the monitor on the left to the left eye, right image from the monitor on the right to the right eye). The images are manipulated on the corresponding monitors with specific offsets so when the observer fuses the two images together, they perceive an image with depth.

Christie Mirage 3D Projector (x2)

In our 3D testing facility Rob Allison and I have two vertically mounted Christie Mirage 3D projectors, with the capability of projecting 120 Hz via dual-link DVI, contrast ration of 2100:1 and a resolution 1920x1200. These projectors can be used individually or simultaneously depending on the experimental requirements.

Polarization-Preserving Stewart Screen

Our 3D projector system is currently used with a 6x10 ft Stewart Filmscreen 150 back projection screen. This screen has excellent polarization preservation, and can be used with both polarized eyewear (plus DepthQ modulator), and active 3D shutter eyewear.
