Dual-Projector All-Harsh-Environmental Proof Housing for Digital Projection TITAN LASER 37000 WUXGA for Architectural 3D Mapping

This is a high-performance, dual-projector protective housing system engineered specifically for architectural 3D mapping using Digital Projection TITAN LASER 37000 WUXGA projectors. The enclosure transforms these ultra-high-brightness laser projectors into permanent, all-weather outdoor installations capable of withstanding extreme environmental conditions while maintaining precise alignment for complex projection mapping.

Specifications & Design Philosophy

• Housed Projectors: 2 × Digital Projection TITAN LASER 37000 (37,000 lumens, WUXGA, Laser Phosphor)

• Primary Application: Permanent outdoor architectural/façade 3D mapping on buildings, monuments, and structures

• Protection Rating: IP65 (Dust-tight & Protected against powerful water jets/temporary immersion)

• Extended Temperature Range: -30°C to +50°C (-22°F to +122°F) operation

• Construction: Marine-grade 316 stainless steel or heavy-duty anodized aluminum with corrosion-resistant coatings

Critical Features for Harsh Environments & 3D Mapping

1. Dual-Projector Precision Alignment System

• Rigid, Unified Chassis: Both projectors are mounted on a single, vibration-dampened monolithic frame to maintain perfect pixel alignment and convergence relative to each other—absolutely critical for edge-blending and geometric warping in 3D mapping.

• Micro-adjustment Mounts: Precision three-point kinematic mounts with micrometer screws for sub-pixel alignment adjustments from outside the enclosure.

• Convergence Locking: Once aligned, the system mechanically locks to prevent thermal or vibrational drift.

2. Advanced, Redundant Climate Control

• Dual-Zone Active HVAC: Independent cooling/heating circuits for each projector compartment, ensuring one projector’s heat doesn’t affect the other.

• Redundant Compressors & Fans: If one cooling system fails, the other can often maintain safe temperatures for both units in a reduced power mode.

• Positive Pressure with Filtration: Maintains slight internal positive pressure with HEPA and carbon filters to keep out fine dust, pollutants, and insects—common in urban mapping environments.

• Condensation Prevention: Active dew point management with desiccant breathers to prevent lens fogging during rapid temperature/humidity changes.

3. Optical Integrity for Mapping Precision

• Anti-Reflective, Heated Optical Glass: High-grade, multi-coated optical glass windows with integrated conductive heating elements to prevent frost, ice, and condensation buildup.

• Low-Expansion Window Frames: Engineered to minimize thermal expansion/contraction that could distort the optical path.

• Internal Blackening & Baffling: Anti-reflective coatings and light traps inside the enclosure prevent internal light scatter and flare, which would reduce contrast—a key factor in mapping depth perception.

4. Harsh Environment Hardening

• Corrosion Resistance: All fasteners, hinges, and seals are marine-grade stainless or brass to resist salt spray, industrial pollution, and acid rain.

• Impact-Resistant Windows: Laminated safety glass or polycarbonate capable of withstanding hail, flying debris, and vandalism.

• EMI/RFI Shielding: Protects sensitive projector electronics from interference in high-RF urban environments (near radio/TV towers, etc.).

5. Integration & Control for Mapping Workflows

• Unified Power & Data Hub: Centralized, sealed pass-through panel for:

  • Dual high-power inputs (often 30A/220V per projector)

  • Signal inputs (HDMI 2.0, DisplayPort 1.4, 12G-SDI for 4K content, dedicated warp/blend network ports)

  • Control (RS-232, RS-485, Ethernet/IP for projector and enclosure monitoring)

• Remote Management Suite: Web interface or software (e.g., compatible with 7thSense, Pandora’s Box, TouchDesigner) to monitor:

  • Internal temperature/humidity of each zone

  • Projector status (lamp hours, laser diode health, errors)

  • HVAC system performance

  • Security alerts (door open, temperature out of range)

• Serviceability: Front or rear large-access panels allow for filter changes, cleaning, and projector maintenance without complete disassembly or disturbing the optical alignment.

Ideal System for Architectural 3D Mapping

• Brute Force Brightness: 74,000 combined lumens can combat severe urban light pollution and map onto large, non-white, or poorly reflective surfaces.

• Absolute Reliability: Enables 24/7/365 operation for tourist attractions, permanent museum displays, or nightly shows, regardless of weather.

• Pixel-Perfect Stability: Maintains complex warps, blends, and masks through thermal cycles and minor seismic activity (wind vibration of buildings).

• Long-Term Cost Savings: Protects a ~$300,000+ investment in projection hardware from environmental decay. Laser light sources already offer 20,000-30,000 hours of life; this housing ensures they reach their full lifespan outdoors.

Installation Scenario

• Mounted on: A dedicated platform, rooftop, or ground-based concrete plinth opposite the target building.

• Alignment Process: Projectors are converged and warped using mapping software (e.g., MadMapper, Resolume Arena) during installation, then the system is sealed. Remote fine-tuning of color and blend is possible via network.

• Content: Driven by a high-performance media server capable of outputting dual 4K signals with real-time warping and blending.
