High speed interface cards for the AR4000 time of flight sensor

The AccuRange High Speed Interface (HSIF) is used to increase the sample rate capability of a AR4000 laser rangefinder while tracking the mirror position on the AccuRange laser line scanner, using any PC-compatible or PC-104 bus computer.

Acuity offers four models of HSIF cards including ones for ISA, PCI and PC104 formats. All cards enable a maximum sampling rate of 50,000 samples per second. A specialized PCI version is even capable of 200,000 samples per second and buffer the data for reading by the host computer.

The high speed interface card from Acuity represents a hassle-free means of increasing the sampling rate of the AR4000 laser rangefinder and tracking the mirror position through the optical encoder on the line scanner.

The board is available with a PCI, PC-104 or ISA bus interface. The AccuRange HSIF includes the interface, user's manual, demonstration / diagnostic software. The input to the card is a pulse-width output (square wave) from the rangefinder. It also takes the lower-level outputs of the laser rangefinder such as AMPLITUDE, AMBIENT LIGHT LEVELS and TEMPERATURE to calculate a calibrated distance reading.

The PCI version of the card is standard with a 64 KB buffer size as well as two motor controllers (voltage controlled) and two single-ended optical encoder readers. The card can be ordered with differential encoder readers as well. The ISA and PC-104 interface cards are standard with a 16K buffer size and a 2-channel motor power control and motor encoder reader.

Acuity offers software developer's kits to be used with the AR4000 in conjunction with the high speed interface cards.
