Methods and systems for detecting optical components are disclosed. An optical signal comprising a plurality of light pulses is transmitted by a laser into a field of view (FOV) of a detector at a pulse repetition rate. A scene within the FOV is depicted to an eyepiece. The detector receives a plurality of reflected light pulses of the optical signal from a location within the scene during a first integration time period of the detector. At least one element of a display that is registered to the FOV is altered based on the plurality of reflected light pulses.

Detection of optical components in a scene

A device comprising a master clock configured to produce a pulse sequence having a wideband light signal of approximately 800 nanometers or red visible wavelength of a predetermined amplitude. The device comprises X laser amplifiers along a common optical path each amplifier being triggered by a burst of X pulses with high-peak power and high-average power. The X laser amplifiers receive the pulse sequence of the master clock and sequentially amplifying the pulse sequence wherein a last laser amplifier of the X laser amplifiers produces an amplified pulse sequence. A compressor is configured to compress the amplified pulse sequence to produce a laser signal having a sequence of directed energy (DE) pulses each DE pulse having a pulse width in a femtosecond range to induce when striking a solid surface of a target object transient electric fields in a microwave frequency range. A system and method are also provided.

Device, system and method with burst mode laser source system forming laser-induced radio frequency (LIRF) energy

A device comprising a low-power oscillator having an oscillator output, the oscillator when triggered produces X number of oscillator pulses in series at a high repetition rate from the oscillator output, where X is an integer. The device comprises a plurality of X series coupled amplifiers having a common optical path. The plurality of X amplifiers amplify a power parameter of the X number of oscillator pulses. A first amplifier of the plurality of X amplifiers is coupled to the oscillator output. The plurality of amplifiers are triggered in sequence in accordance with the high repetition rate of the oscillator so that an output from a last amplifier of the plurality of X amplifiers is a burst of X amplified pumping oscillator (APO) pulses with high-peak power and high-average power over the burst of APO pulses. A system and a method are also provided.

Device, system and method with cascaded burst mode laser amplified pumping oscillator signal

A solid nose cone and related components are disclosed. Embodiments include a front-end system for a laser-guided munition. The front-end system includes a solid nose cone that is optically transparent to electromagnetic radiation (EMR) of a particular wavelength. The solid nose cone is configured to pass EMR incident on the exterior surface to the trailing end. An optical relay adapter (ORA) has an EMR-receiving front face and an EMR-emitting rear face. The EMR-receiving front face is optically coupled to the trailing end, and the ORA is configured to relay the EMR from the EMR-receiving front face to the EMR-emitting rear face.

Solid nose cone and related components

An aerodynamic conformal nose cone and scanning mechanism is disclosed. Laser energy, from within a body of a missile, is directed through a solid, optically transparent nose cone. A detector in the body detects reflected laser energy that passes through the solid, optically transparent nose cone.

Aerodynamic conformal nose cone and scanning mechanism

The presently disclosed technique presents laser-based method and apparatus for use in remote sensing. In general, objects within a field of view are lased by a long cavity laser apparatus. Returns are detected, captured, and processed to identify actual objects of interest. These can then be communicated to a user. Over time, the actual objects of interest can be auto-tracked.
