Abstract: An optical channel monitor is provided that sequentially or selectively filters an optical channel(s) 11 of light from a (WDM) optical input signal 12 and senses predetermined parameters of the each filtered optical signal (e.g., channel power, channel presence, signal-noise-ratio). The OCM 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates spatially each of the optical channels 11 of the collimated light, and reflects the separated channels of light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the channels of light back through the collimating lens 18. The lens 18 focuses each separated channel of light (λ1-λN) at a different focal point in space. One of the optical channels 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each optical channel 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

Abstract: The monochromator has, as a beam-diffracting element, a scanning mirror (3) which is fastened on a vibratory spring, preferably a spring-steel strap (8), clamped on one side. The vibratory spring is oscillated by way of an electromechanical self-energized oscillation circuit, a sensor (11a, 11b) which detects the deflection of the vibratory spring (8) is provided and whose output signal is used as a feedback signal for maintaining the oscillation of the vibratory spring (8). The amplitude of oscillation of the oscillating element can likewise be varied. With such a design it is possible to produce simply and inexpensively a monochromator with which a considerable spectral range can be swept and, in addition, the width and position of said spectral range can be variably adjusted.

Abstract: The present invention provides a wide-filed spectral imaging system including a laser generator, a wavelength adjustment module, an objective lens, and a single-pixel imaging and a spectral separating module. The laser generator is configured to generate a laser excitation beam. The wavelength adjustment module is configured to disperse the laser excitation beam into a plurality of beams of different wavelengths. The objective lens is configured to focus the plurality of beams of different wavelengths on a sample to excite molecules under test in the sample and generate an emission light. The single-pixel imaging and spectral separating module is configured to generate a series of patterns and modulate the emission light with the series of patterns to generate a diffracted beam. The single-pixel imaging and spectral separating module further disperses the wavelength of the diffracted beam, collects light signals of the expanded diffracted beam, and performs a spectral image reconstruction.
