An integer division circuit includes a first bit-shifting circuit configured to shift the bits of a dividend to produce a normalized dividend. The circuit also includes a second bit-shifting circuit configured to shift the bits of a divisor to produce a normalized divisor. A divider tree circuit is configured to divide the normalized dividend by the normalized divisor to produce a normalized quotient. The circuit further includes a third bit-shifting circuit configured to shift the bits of the normalized quotient to produce a quotient.

Integer division circuit and method of performing integer division in hardware

A multi-ladar sensor system is proposed for operating in dense environments where many ladar sensors are transmitting and receiving burst mode light in the same space, as may be typical of an automotive application. The system makes use of several techniques to reduce mutual interference between independently operating ladar sensors. In one embodiment, the individual ladar sensors are each assigned a wavelength of operation, and an optical receive filter for blocking the light transmitted at other wavelengths, an example of wavelength division multiplexing (WDM). Each ladar sensor, or platform, may also be assigned a pulse width selected from a list, and may use a pulse width discriminator circuit to separate pulses of interest from the clutter of other transmitters. Higher level coding, involving pulse sequences and code sequence correlation, may be implemented in a system of code division multiplexing, CDM. A digital processor optimized to execute mathematical operations is described which has a hardware implemented floating point divider, allowing for real time processing of received ladar pulses, and sequences of pulses.

LADAR sensor for a dense environment

An optical device and method providing multi-channel bulk optical power monitoring is disclosed. The device and method may include a scanning mirror, a plurality of input optical fibers, a plurality of output optical fibers, and at least one sample optical fiber optically connected to a photodetector. The device and method may further include a first reflective surface and a second reflective surface. The first reflective surface may reflect light from the input optical fibers to the second reflective surface. The second reflective surface may reflect a first portion of the light into the output optical fibers and pass a second portion of the light to the scanning mirror. The scanning mirror may reflect samples of the second portion of the light into the at least one sample optical fiber.
