Abstract
Systems and methods for confocal imaging are described. In one implementation, a confocal imaging system may include a light source configured to emit excitation light having one or more wavelengths, a sample holder configured to hold a sample, a two-dimensional (2-D) imaging device, a first set of optical elements, and a second set of optical elements. The first set of optical elements may include a first spatial light modulator (SLM) and at least one lens. The first set of optical elements may together be configured to collimate the excitation light, apply a predetermined phase modulation pattern to the collimated excitation light, and illuminate the sample in an excitation pattern.
