A smoke detector that is insensitive to moisture, such as for use in aircraft cargo bays and the like, is provided. The smoke detector includes a housing defining a chamber that is sealed from outside light sources yet is capable of receiving smoke. The smoke detector also includes a light source that is positioned inside the chamber and a detector for receiving diffusely scattered light within the chamber. Advantageously, the smoke detector also includes a moisture compensating device that reflects a substantially consistent percentage of light incident thereupon regardless of moisture on the surfaces thereof such that the operation of the light source can be reliably tested even in environments where moisture has condensed or otherwise collected on the walls of the housing.

Chirped synthetic wave laser radar apparatus and methods are disclosed. In one embodiment, a system includes a laser source, a controller operatively coupled to the laser source and adapted to frequency-modulate first and second laser outputs, and an optical assembly. The optical assembly includes a plurality of reference channels adapted to receive a portion of a combined laser output and to provide a reference interference signal, and a signal channel having a focusing telescope adapted to focus and transmit at least part of the combined laser output onto the target, and to receive a scattered signal from target, and to provide a return interference signal. The system further includes a signal processing portion adapted to receive the reference interference signals and the return interference signal and to determine the distance to the target based on the reference and return interference signals.

Systems, methods, and computer program products are provided for accurately measuring frequency-and/or-phase-related parameters of a sinusoidal signal that varies non-linearly in frequency or phase. A sinusoidal signal is sampled over a finite period of time at a plurality of sample points. The sampled signals are pre-processed, and a Fourier transform is performed on the pre-processed sampled signals. Phases of the pre-processed sampled signals are extracted from the Fourier transform, and a measurement indicative of frequency of the sinusoidal signal is determined from slope of the phases of the pre-processed sampled signals. Range to a target may be determined using the exemplary signal processing described above on laser radar interference signals.

A Doppler velocimeter apparatus and method of forming same. In one implementation a coherent light source is used for generating a beam of coherent light. An optical fiber receives the beam of coherent light. The optical fiber has an output face that is generally flat, thus enabling a first portion of the beam of coherent light to be reflected back on the optical fiber and to form a frequency offset, while a second portion of the beam of coherent light exits the optical fiber. A mechanism is used to move the output face of the optical fiber in an oscillating fashion so that the first portion of coherent light reflected back on the optical fiber produces an oscillating waveform that forms a frequency offset. An optical element receives the second portion of light from the face of the optical fiber and transmits it to a subject, and then receives a reflected optical signal back from the subject. The reflected optical signal, when mixed with the oscillating frequency offset, produces a Doppler shift that is dependent on the motion of the subject.

Systems and methods are provided for targetless optical measurement and optical information projection. A non-contact optical measurement device is provided for determining at least one of position and orientation of a workpiece. A projector is provided for projecting a part definition on the workpiece. Advantageously, beams from the non-contact optical measurement device and the projector pass through common optics.

Systems and methods to control projection of a pattern are provided. A particular method includes receiving first three-dimensional coordinates that specify one or more locations on a surface of a workpiece where the one or more locations correspond to a part definition to be projected onto the surface. The method also includes computing scan angles for a scanning system based on the first three-dimensional coordinates. The scan angles specify angles used by the scanning system to direct a beam of light to project the part definition onto the surface. The method also includes sending control signals to the scanning system based on the scan angles.

A Doppler velocimeter apparatus that may have a coherent light source for generating a beam of coherent light. A modulating subsystem may receive and modulate at least a first portion of the beam of coherent light to form a first beam portion, the first beam portion forming a frequency offset and being a modulated, coherent optical signal. An optical element may receive the first beam portion and direct the first beam portion at a subject, the first beam portion being reflected from the subject to form a reflected beam that has a frequency that is modified in relation to the motion of the subject. A processing subsystem may receive a second portion of the beam of coherent light, and also the reflected beam, and uses the second beam portion and the reflected beam to determine a Doppler shift of the reflected beam.
