This page describes the hardware component of image generation and the reconstruction process.
Experimental Setup
Image: Materials used in the benchtop setup. a) Camera sensor. b) LED. c) Customized aperture. d) Put the aperture onto the sensor.
Our hardware setup diverges from traditional lens-based approaches by utilizing a diffuser mask to scatter light onto the sensor, creating a distinct caustic pattern. The setup features a Thorlabs CMOS scientific camera sensor CS165MU1 controlled via ThorCam software, with a customized cardboard aperture positioned near the sensor. Additionally, a Thorlabs LED MCWHL7, fitted with an iris, provides the light source, while a lens tube blocks ambient light. The forward model characterizes the optical imaging system physics, solving the inverse problem to reconstruct the object from the image. This involves a 2D object matrix denoted as s(x,y) and a PSF denoted as h(u,v), with the resulting image I(u,v) being the convolution of the PSF and object.
