Abstract In this work we demonstrate a miniaturised imaging system based around a time-gated SPAD array operating in a “chip-on-tip” manner. Two versions of the system are demonstrated, each measuring 23 mm × 23 mm × 28 mm with differing fields

Wavelength-to-time mapping (WTM)—stretching ultrashort optical pulses in a dispersive medium such that the instantaneous frequency becomes time-dependent—is usually performed using a single-mode fiber. In a number of applications, such as time-st

We present an ultrafast laser fabricated end-cap for use with polymer imaging fibres. The end-cap enables optical sectioning of the imaged sample and reduces back-ground fluorescence from both the sample and the fibre itself.
