Background: What is a phase plate? A phase plate is a diffractive optical element (DOE) that superimposes a certain pre-designed phase profile on an input laser beam. Such a phase profile can be binary (by creating a half-wave delay between certain areas of the phase plate) or continuous (reaching up to a full wave delay). … Continue reading
Particle Imaging Velocimetry (PIV) is a non-intrusive, laser optical measurement technique used in research and diagnostics of flow turbulence, microfluidics, spray atomization, and combustion processes. Particle imaging velocity measures the entire region within the flow with simultaneous measurement of its velocity. The basic principle includes photographic recording of the motion of microscopic particles that follow … Continue reading

Background: What is a diffractive beam splitter? Diffractive beam splitters, or multi-spot elements, are a family of diffractive optical elements (DOEs) that split an incoming laser beam into an array of beams with controlled separation angles. This splitting can be along a line (1-D splitters) or into a matrix (2-D splitter), including square, hexagonal or rectangular array … Continue reading
